Question

What is √36ab^4c^5 ?

Answer 1

You'll need to use parentheses to indicate what is under the first radical sign and what is not. Did you mean radical(36a) or just radical 36?

I will assume that you meant radical(36a).

Then you have [radical(36a}*(b^4)*c^5.

This comes out to 6sqrt(a)*b^4*c^5.
