1. Simplify 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: 16^12/x^6?
4. (2/b^5)^3
My answer: b^15/8?

#1 nope. If you subtract 3 from 9, you don't get 6.
4 x 10^12
#2 yes
#3 (4y^6/x^3)^2 = 16y^12/x^6
#4 yes
