Which expression is equivalent to (r^-7)^8
ahrayia [7]

Answer:

1/r^56

Step-by-step explanation:

Not sure if you did a typo there or what cus 7 x 8 should be 56

Whenever the power of a number is negative, you flip. So r^-7 becomes 1/r^7

Remove the bracket and distribute 8 to the power of 1 and r^7

1 to the power of 8 will still be 1, r^7 x 8 = r ^ 56
