Best ResponseYou've already chosen the best response.0using this you take the first variable of the first and multiply it by the second parenthesis and same with the second variable/constant of the first \[a(a2)+3(a2)\]

Best ResponseYou've already chosen the best response.0the power tells you how many times you multiply that base by itself

Best ResponseYou've already chosen the best response.0so \[2^3=2*2*2\] \[2^5=2*2*2*2*2\]

Best ResponseYou've already chosen the best response.0so in your case \[ a*a\] a is your base and the number of bases you multiply is your power

Best ResponseYou've already chosen the best response.0I think it's just the variable thats giving you a tough time if it helps let a be whatever you want and then replace it back with a. For example i have \[a*a*a*a\] in your head think a=5 \[5*5*5*5=5^4\] replace 5 with a
