Question

Please help me solve for the letter !!!!!!!!!!!!!!

Answer 1

it may be 34 because the 34 to the second power is 68

Answer 2

d = 2
`√(7)`

Explanation:

You want to solve for d by itself, so you must take the square root of both sides.

d =
`√(68)`

This can be simplified, since this square root has a perfect square inside. You take out the perfect square (which is 4) and end up with 2
`√(7)`
