You can put this solution on YOUR website! 1. Simplify the expression.
square root -128 square root -16
= (8sqrt(2)i (4i)
----
= -32sqrt(2)
=====================
4.Multiply the expressions, and simplify.
(2x^-4y^-4) · (-7x^4y^-2)
= -14x^0*y^-6
-----
= -14/y^6
============
5.Short Answer: Simplify the following expression, and rewrite it in an equivalent form with positive exponents.
(6x^-1)^-2
= (1/36)x^2
===============
6.Raise the quantity in parentheses to the indicated exponent, and simplify the resulting expression.
(-2x^9y^4)^4
---
= 16x^36y^16
