What is 10 to the fourth power?

In the expression 10^4, 10 is the base and four is the exponent. Whenever 10 is the base, the expression is quickly simplified by writing a one followed by the number of zeros named by the exponent. In the above example, 10^4 is written as one followed by four zeros, or 10,000. The expression 10^2 power is written as one followed by two zeros, or 100, and 10^3 is written as one followed by three zeros, or 1,000.

What are some names of shapes?

Polygon is a geometric term that refers to a closed shape made of straight line segments. Some prominent polygons in ascending order of sides are the triangle, quadrilateral, pentagon, hexagon and octagon. Most polygons used in geometry are subdivided by more characteristics than just number of sides. For example, four-sided shapes (quadrilaterals) can be further divided into rectangles, squares, parallelograms, kites and trapezoids.\nShapes made out of curves are not considered polygons, although they are used in geometry. Circles are the best-known curved shapes, and pieces of circles are ca..

Who came up with pi?

Before pi became widely used, the ratio was called "quantitas in quam cum multiflicetur diameter, proveniet circumferencia" a phrase that is Latin for "the quantity which, when the diameter is multiplied by it, yields the circumference." The fractions 355/113 and 22/7 were often used for pi. However, those ratios are not an accurate representation of the true ratio of pi.

Is there an online withholding calculator available?

Each of these sites provides a slightly different set of input options and results. Kiplinger uses a simple 3-question form and recommends changes to the number of withholdings to maximize take-home pay.\nTurboTax, ADP and the IRS require detailed information from previous tax returns and paycheck stubs. They inform the taxpayer how to properly fill out the W4 form to achieve desired income. Tax information changes each year, so taxpayers need to be sure the withholding calculator they use is for the correct tax year.

How do you multiply fractions with different denominators?

Write out your equationStart by writing out your equation. For example: 1/4 x 4/5 = X.Multiply the numeratorsMultiply the first numerator by the second numerator. The product of the two numerators becomes the numerator in the answer. For example, in the equation 1/4 x 4/5 = x, multiply 1 x 4 to get 4 as the numerator.Multiply the denominatorsMultiply the first denominator by the second denominator. The product of the two denominators becomes the denominator in the answer. For example, in the equation 1/4 x 4/5 = x, multiply 4 x 5 to get 20 as the denominator. Written together, the multiplied f..

Is zero a real number?

Zero is neither a positive nor a negative number and doesn't follow the normal set of rules used in math. In multiplication and division, 0 multiplied or divided by any other number is always equal to 0. In addition, a number added to 0 results in the exact same number. In subtraction, 0 produces the same effect as with addition when 0 is subtracted from a number. If a number is subtracted from 0, the result is the negation of the number. Zero is used to also show the empty places in the ones, tens and hundreds places.

What is the square root of 3,600?

Finding a square root is the inverse of finding the square of a number. Squares are derived by multiplying numbers by themselves. A perfect square occurs when the square root of a number is a whole number. For example, 3 x 3 = 9, and the square root of 9 is 3. Numbers that end in decimal points or fractions are imperfect squares. The symbol used to denote a square root in the world of math is called a radical.

What are all of the possible 4-digit combinations for a phone with 0 - 9 with repeat?

According to Math Is Fun, permutations with repetition are the easiest to calculate. The person needs to determine the number of dial pad numbers she can choose from (n) and the number of selections (r). In this case, to calculate a 4-digit number with numbers 0 through 9 available, there are 10 available dial pad numbers (n=10) for each digit with four digits selected (r=4). The number of permutations can be calculated with the formula n^r, in this case by multiplying 10 x 10 x 10 x 10.\nWhen repetition is not allowed, the permutation formula is adjusted to the factorial function, which is no..
