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

<em><u>The expression becomes:</u></em>

6 + 2^1 = 8

Here we have used one operation, that is addition

Verifying the expression

6 + 2^1 = 6 + 2 = 8

Thus the required expression is found
