Can you take the square root of both sides of an inequality

Hi there!

Since square roots are non-negative, Inequality is only meaningful if both sides are non-negative. Hence, squaring both sides was indeed valid.

Similarly, applying a decreasing function toboth sides of an in- equality will reverse it.

Cheers!

I was told that the answer to this is -7 but I don't understand how to get there.
Amiraneli [1.4K]

Answer:

The answer to your question is: - 7

Step-by-step explanation:

                                            3125 = (- 1  - 18t) ⁵/³

                                            (3125)³ = ( -1 - 18t)⁵

                                            (3125)³/⁵ = - 1 - 18t

                                            125 = - 1 - 18t

                                            125 + 1 = - 18t

                                            126 = - 18t

                                            t = 126 / -18

                                            t = -7

3125³ = 3.0518 x 10¹⁰

\sqrt[5]{3.0518 x 10¹⁰} = 125
