simplify (9x8y3)1/2

This could mean a couple different things.

This could mean

Simplify: (9*8y*3)1/2                --- * means times

...or

Simplify: ((9x)*(8y)*(3))1/2

 

I'm thinking you meant the first one: (9*8y*3)1/2

(9*8y*3)1/2           

(72y*3)1/2

(216y)1/2

108y

 

So 108y would be the simplified version.
