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

Answer 1

\[\sqrt{p^6} + \sqrt{9p^6} + 3\sqrt{p^6} - \sqrt{p^2}\]

Answer 2

Thats the expression above

Answer 3

To add terms you need the exponent to be the same

When the power is an even number inside a radical, you can cut it in half and get rid of the radical
\[\sqrt{x^{2n}} = x^n\]

Answer 4

what do i do next? from there?

Answer 5

add like terms

\[\rightarrow p^3 + 3p^3 +3p^3 - p\]

Answer 6

\[7p^3 - p\]

Answer 7

is what i got

Answer 8

@dumbcow is that it?
