Choose the correct simplification of the expression (7ab^3)^2. 49ab^6 49a^2b^5 49a^2b^6 14a^2b^6
no guesses this time lol @seiga can u explain ?
its not a guess,.its the answer.
f you have something raised to a power you mutliply the exponents. If it doesn't have an exponent than you can place an understood 1 as the exponent. (7^1*2)(a^1*2)(b^3*2) or (7^2) (a^2) (b^6) simplify 49a^2b^6 or the third one. Hope I helped :)
thanks ! and sorry i normally have a guess on what the answer is. satellite asked if i had one.
