Question 418054: I am not sure what to de here! Multiply and simplify by factoring. Assume that all expressions under radicals represent nonnegative numbers sqrt 28a^5b * sqrt 8a^6b^4 Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! sqrt 28a^5b * sqrt 8a^6b^4
---
= sqrt[28*8*a^11*b^5]
---
= sqrt[4*4*7*2*a^10*b^4*ab]
---
= 4a^5b^2*sqrt[14ab]
