x^2 * x^5 = x^(2+5) = x^7 you don't get (x^2)^7
Eden did it correctly, Erin instead of adding the exponents multiplied them, and Emma added the exponents but multiplied the factors when she should have left them alone.
Emma did not solve it correctly. The laws of exponents say that a^m * a^n = a^(m+n) So the base a does not need to be multiplied.
So Eden did it correctly?
yes
ok thanks
