Best ResponseYou've already chosen the best response.0So we can substitute 2^3 for 8 right. It becomes 2^(x+1)=[2^3]^(x2). The right hand side can be simplified 2^(x+1)=2^3(x2) Since the bases are the same, the exponents must be equal.

Best ResponseYou've already chosen the best response.0Did you equate the exponents: Like if i say a^x=a^y, x must be equal to y. So in our case x+1=3(x2)

Best ResponseYou've already chosen the best response.0Yes. Do you see how the substitution helped? It made the bases the same so we can conclude that the exponents are equal
