Question

Write 15*15*15*15 using an exponent

Answer 1

15^4

Explanation:

An exponent refers to the number of times a number is multiplied by itself,

so 15 multiplied 3 more times by itself (15 * 15 * 15 * 15) its 15^4.

Answer 2

`15^(4) .`

Explanation:

1. General concept about exponents.

When working with positive non fractional exponents, we state that a number A elevated to the n power is that number A in a multiplication of itself n times. For example, when we write
`7^(3)` we're stating that the seven is being multiplied 3 times:
`7*7*7`.

2. Use the rule to rewrite the expression.

As you may see, the expression "15*15*15*15" is just the number 15 being multiplied by itself four times. Hence, we could say that the number 15 to the power of 4. Thus, we can rewrite it as:

`15^(4) .`
