Question

Find the exact value of the radical expression in simplest form.
the square root of p to the sixth power + the square root of 9 times p to the sixth power + 3 the square root of p to the sixth power − the square root of p squared

13 times p cubed times the square root of p − 2 times p times the square root of p

13 times p cubed times the square root of p − 2p

7p3

7p3 − p

Answer 1

ok easy way to think of these
divide the power by the root, square root means the root is 2
6/2 = 3
\[\sqrt{p^{6}} = p^{6/2} = p^{3}\]
