Simplify the expression. Write your answer using only positive exponents.
Explain as well.
1. (8x)^3*8^4
2. 2x^5*y^3
3. (4x^4y^3)^2
4. 1/(3x)^2

1. (8x)^3*8^4 = 8^3*x^3/8^4 = x^3/8
4. 1/(3x)^2 = (3x)^2 = 9x^2
Now you try the others. Get rid of negative exponents by moving those terms from numerator to denominator, or vice versa.
