Consider the given expression (−3)4.

Since the power is 4, multiply −3 four times to compute the value of (−3)4.

(−3)4=(−3)×(−3)×(−3)×(−3)=9×9=81

Thus, the value of (−3)4 is 81.

Consider the given expression −34.

Since the power is 4, multiply 3 four times to compute the value of −34.

−34=−(3)×(3)×(3)×(3)=−9×9=−81

Thus, the value of −34 is −81.

Consider the given expression 3−4.

Since the power is −4 , multiply 13 four times to compute the value of 3−4.

3−4=(13)×(13)×(13)×(13)=19×19=181

Thus, the value of 3−4 is 181.

Formula used:

The a is real number and m, n are natural numbers then aman=am−n.

Calculation:

Consider the given expression 523521.

Use the above mentioned formula compute the value of 523521.

523521=523−21=52=25

Thus, the value of 523521 is 25.

Consider the given expression (23)−2.

Since the power is −2 , multiply 32 two times compute the value of (23)−2.

(23)−2=(23)−1×(23)−1=32×32=94

Thus, the value of (23)−2 is 94.

Consider the given expression (16)−34.

Since the power is −34 , multiply 116 three fourth times compute the value of (16)−34.

(16)−34=(116)34=((12)4)34=(12)3=18

Thus, the value of (16)−34 is 18.
