#1 nope. If you subtract -3 from 9, you don't get 6.
4 x 10^12
#2 yes
#3 where did b come from? I suspect you mixed up problems.
(4y^6/x^3)^2 = 16y^12/x^6
1Simplify the quotient (6.4 x 10^9) / (1.6 x 10^-3). Write the answer in scientific notation.
My answer: 4 x 10^6?
Simplify.
2. a^16/a^4
My answer: a^12?
3. (4y^6/x^3)^2
My answer: b^15/8?
