2^4 *2^5 / 2^7-2^4 = ?
I get 2^9/2^3= 2^6
what did i do wrong?
qa is -12

Appetite for 700 and I scraped my plate!
hey... you can't subtract exponents with the same base.
All you could do is factor out like this
2^4 *2^5 / 2^7-2^4 =
2^9/2^4(2^3 - 1) = (factored 2^4 in the denominator)
2^5/(2^3 - 1) = you can only subtract exponents when they are divided
