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

1 answer:

6 0

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.

Explain how u can decide where to place the first digit of the answer for 6,139 / 153

storchak [24]

Answer:

The first digit would go in the tens place.

Step-by-step explanation:

First we estimate the approximate numbers. For 6130 we estimate 6000 and for 153 we estimate almost 150.

So dividing 6000 by 150 would give 40 .

The four would go in the ten's place .

Now check by dividing

40.1 So the answer is correct. The quotient is 40.12.

$153\sqrt{6139}$

612

190

153

37

The first digit would go in the tens place.

The answer is justified. We can easily decide where to place the first digit.
