In general, we can write the value in decimals by observing the exponent. When the exponent is negative, we can apply the rules of exponent, x -a = 1/x a, and find the value.įor example, 10 -4 = 1/10 4 = 1/10000 = 0.0001 The number of zeros in the product is equal to the exponent. When the exponent is positive, we can write the power in the expanded form and find the product.įor example, 10 4 = 10 × 10 × 10 × 10 = 10,000. The exponent of a power of ten can be a positive or negative integer. The exponent of the power tells us how many times the number is multiplied to itself.įor example, when the exponent is 3, we multiply 10 by itself 3 times.ġ0 3 = 10 × 10 × 10, this is also called the expanded form of the power.

Power of any number is an expression that represents repeated multiplication of the number. 10 n is read as “10 to the power of n.” Expanded Form The exponent can be any integer (positive, negative, or zero).įor example, 10 n has base 10 and exponent n, where n is an integer.

The exponent tells us how many times the base is multiplied by itself.

The base of power tells us what number is being multiplied.

Like any other exponential form, a power of 10 consists of a base and an exponent, as shown below. When we multiply 10 by itself a certain number of times, we can express that in an exponent form, also called the power of 10. Let’s explore more about them right away! What is the Power of Ten?Īn exponent of a number indicates how many times we multiply a number by itself. When we multiply 10 by itself a certain number of times, we call it the power of ten.

Also, the number of zeros in the product of each equation is the same as in the number of tens multiplied together. Each equation is ten times more than the previous one. Kelly wrote a few equations on the board and asked her students to look for a pattern in them.
