Best ResponseYou've already chosen the best response.2or you can factor x^3 remember exponent rule when you multiply same bases you should add their exponents \[\huge\rm x^m \times x^n = x^{m+n}\] so you can write \[\large\rm x^3 = x \times x \times x \]

Best ResponseYou've already chosen the best response.2^^yep x times x can be written as = ??? hint exponent rule x^m times x^n = x^{m+n}
