Use the number 8,6, and 2 and one operation to write an expression that includes an exponent and has a value of 8. use each number only once.

is the expression that includes an exponent and has a value of 8

Solution:

Given that, Use the number 8, 6, and 2 and one operation to write an expression that includes an exponent and has a value of 8

We have to use each number only once

Given numbers are 8, 6, 2

Our expression should include exponent and the result should be 8

Among 6 and 2 we can use 2 for exponent

Raise 2 to power of 1

The expression becomes:
