Umm, another question. At 9:37 you put down 3^2x [ 1+3^x+3^2x]=y but shouldn't it be 3^2x [ 1+1^x+1^2x]=y? b/c if I were to multiply your equation out again I'd get 3^2x+9^3x+9^4x.
I don't know, I had a horrible math teacher so I'm just really confused...
But your vids are acctually really helpful with all the rules explained and sat tips!

For the last problem, I seriously thought (a) was the answer. O.o

I'm confused, at 7:46 roughly you solve for a and for b. But the problem said to solve for ab right? So do I multiply 16 and 1/2 or add them?
