Question

Keeping the properties of exponents in mind, to what power must you raise the expression 7 1/2 to get 7 as a result

Answer 1

For this case we have the following expression:
 $7 ^ {(1/2)}$
 Rewriting the expression we have:
 $(7 ^ {(1/2)}) ^ x$
 Where,
 x: exponent to which we must raise the expression to obtain 7 as a result.
 We have then:
 $7 ^ {((1/2) x)}$
 The exponent must be equal to 1:
 $(1/2) x = 1$
 Clearing x we have: 
 $x = 2$
 Substituting valres:
 $7 ^ {((1/2) 2)} 7 ^ 1 7$
 Answer:
 you must raise the expression to 2
