    replace b with a^3 b^2 = c (b)^2 = c (a^3)^2 = c I'll let you finish up

    I replaced b with a^3 because the first equation is a^3 = b or b = a^3 a^3 is the same as b, which is why the replacement can be done

    you'll use \[\LARGE (x^a)^b = x^{a*b}\]

    eg: \[\LARGE (x^8)^5=x^{8*5}=x^{40}\]

    yeah you'd most likely learn that in alg 2
