Okay the problem says I have to multiply (-2t)^2(3t^7)^2

Question

SO what am I supposed to do, add the exponents then multiply -2t by 3t? Geez this is so confusing. If I square everything inside the first parentheses by 2 I get (4t^2)
the second parentheses would be (
(9t^9) ?
then it should be 36t^11?

Answer 1

(-2t)^2(3t^7)^2
= (4t^2)(9t^14)
= 36t^16

just follow the rules you learned
