Multiply Radicals

Question

√14m⁵√7m⁵

 

So, what I was taught is to multiply through, so 14*7 and m⁵*m⁵ which would give me √98m¹⁰

 

I don't know where to go from there.   

Answer 1

That step is correct now you want to look at 98m¹⁰ to see if that can be simplified.

 

That means can you factor it into "pieces" that have an "exact" square root.

 

e.g 98 = 49*2 and m¹⁰ = (m⁵)².

 

 

Do you know where to go from here?
