Question 85519
the first one is,Write 3cd^3(to the third power)as a multiplication expression.
= 3*c*d^3
===================

The next one is,Simplify:5c^-5 d^-1
= 5/[c^5 d]
================


Next is,Simplify:(11cd)(2c^2d)(d)

= 22c^3 d^3
---------------

And the last one is,Simplify:(3x^4y)(xy^2)
= 3x^5y^3
=====================
