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

  • Math Uugghhh -

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

    just follow the rules you learned
