Question

How do you solve this?

x^4<=80

Answer 1

take the 4th root on both sides?

Answer 2

But what do you do with the inequality signs?

Answer 3

ok i'd break it down to \(x^2\le\sqrt{80}\) and \(x^2\ge-\sqrt{80}\) which is rejected

Answer 4

Then I'd break \(x^2\le\sqrt{80}\) into \(x\le\sqrt[4]{80}\) and \(x\ge-\sqrt[4]{80}\).

Answer 5

Thank you!

Answer 6
