Brainiest to first answer Simplify the expression (4xy^2) ^4 (-y) ^-3

4 to the fourth is 256. x to the fourth is x^4. t squared to the fourth is y^8. - t to the third is - y^ - 3. So out negative sign out front and use the law of exponents to the 8 and - 3 y exponents and the answer is (-256x^4) * (y^5)
