Question

Get confused with all the powers??? Answer??

Answer 1

Hello There!

The rules with powers or exponents are:
If you multiply, you add them
If you divide, you subtract them
And if you multiply with brackets, you multiply the numbers.
Therefore this is what you get:
49$d^{16}$

Hope This Helps You!
Good Luck :)

Answer 2

(7d^8)²

7 x 7 = 49

(d^8)² = d^64

d^64 + 49 is your answer

hope this helps
