Question

What is the simplified form of the expression 5√v^8-v^3-√16v^8+3√v^3
a: 9v^6√v
b: 9v^4√v^3
c: v^4+2v√v
d: 2v√v^5

Answer 1

\[\sqrt{v^8} = v^4\]
\[\sqrt{v^3} = v \sqrt{v}\]
\[\sqrt{16v^8} = 4v^4\]
\[3v^3 = 3v \sqrt{v}\]

Answer 2

still need help?

Answer 3

@nphuongsun93 that can't be

Answer 4

which can't be o.o?

Answer 5

the answer you gave

Answer 6

@dpaInc yes

Answer 7

\[\sqrt{v^8} = \sqrt{v^4 * v^4} = v^4 \]
agree?

Answer 8

yeah

Answer 9

\[\sqrt{v^3} = \sqrt{v*v*v} = v \sqrt{v}\]yes?

Answer 10

yes

Answer 11

can you do it now? o.o

Answer 12

After what nphuong gave you, you have 5v^4 - vsqrt(v) - 4v^4 + 3vsqrt(v). Do you know how to combine like terms? After you do that, you're all done.

Answer 13

i got c

Answer 14

You're right :)
