48 is 16 x 3

Take the square root of 16 =4

4 square root of 3

Now look at n^9

that can be written as n times n^8

n^4 comes out and leaves n under the square root sign.

your answer should be

4n^4 square root of (3n)

One way to get an better understanding of this concept is to think of square root as... "For every two things that are identical under the square root one comes out.

√(48n^9)

= √16 *√3*√n^8 *√n

= 4n^4 √(3n)
