Answer 2

Concept:

The number of times a number is multiplied by itself is referred to as an exponent. The power of a number is also known as the exponent. It can be any type of number, including whole numbers, fractions, negative numbers, and decimals.

Given:

7⁴k = |100|

Find:

The value of k.

Solution:

7⁴k = |100|

2401*k = ± 100

k = $\frac{100}{2401} or \frac{-100}{2401}$

Hence, the value k is  $\frac{100}{2401}$  or  $\frac{-100}{2401}$.
