How do you solve sqrt(m+2)<sqrt(3m+4)m+2<3m+4?

m > -1m>1.

Explanation:

If we square both sides, we can get:

(sqrt(m + 2))^2 < (sqrt(3m + 4))^2 (m+2)2<(3m+4)2

m + 2 < 3m + 4m+2<3m+4

-2m < 22m<2

We now divide both sides by -22, not forgetting to switch the direction of the inequality symbol.

m > -1m>1

We now test our answer to see if it is true. Let m = 1m=1.

sqrt(3) < sqrt(7) color(green)(√)3<7

This is obviously true.

Hopefully this helps!
