Question

What is a simpler form of the radical expression?
I need someone to check my answer!

Answer 1

It either 7|x^3|y^4 or 7x^3|y^4| I'm pretty sure it's the first one right?

Answer 2

Work out what 4th root 2401 is and the rest is probably more straightforward.

Answer 3

Well, remember that \(|y^4| = y^4\) since anything to an even power is going to be positive.

Answer 4

This isn't the case for \(|x^3|\) which is why the absolute value bars must stay.

Answer 5

Answer 6

@Trillography Given what I said, you can figure it out with certainty, right?

Answer 7

Dude, both of my answers that I think are right have A.V. bars ...

Answer 8

Was going to say 3 or 4 but now I've got it.

Answer 9

Cheers wio. ;D

Answer 10

-x * -x * -x does not equal -x * -x
Good luck. BTW are we answering your monday maths homework? You've asked a few questions.

Answer 11

No, your definitely not. I've already finished all my hw. I'm working on a p. exam. I've asked more than a few and about 80% of them didn't get answers.

Answer 12

Ok 'x' flips its sign, potentially, if it starts out negative. As does the 'y' term. However, the 'y' term is multiplied an even number of times - whereas the 'x' term is multiplied an odd number of times.

Answer 13

So:
-1*-1=1
-1*-1*-1=-1
-1*-1-*1-*1=1

So by using the bars i.e. the absolute value we get answer (c.) that is 1 from zero.

Be it +1 or -1
