Answer 1

Mistake.
I believe the expression is
(7q^2)^3 correct?

Answer 2

Yes sorry I coped it from a different question and forgot to do that

Answer 3

*copyed

Answer 4

If yes then you will have to multiply the exponents to be simplified.

Therefore:
(7q^2 * 3) we multiply the exponents 3 and 2
So 3* 2 = 6
And now we will have to multiply 3 by the coefficient 7
3 * 7 = 21
So the new expression would be
21q^6
Hope that helps

Answer 5

I guess it is (7q^2)^3 then 7^3*q^(2*3) is the answer

Answer 6

Made a mistake it should be
343q^6

For the coefficient we multiplied the exponents si we had
7^3 which means it is 343 not 21
