Which two square roots are used to estimate 42.

A. 25 and 36***
B. 36 and 49
C. 49 and 64
D. 25 and 64

Since when does 42 lie between 25 and 36 ???

Well think about it where does 42 lie between? 36 and 49 therefore the answer would be option 2 / B

Well, if we're estimating the square root of 42, we need to find two numbers whose square roots are close to it. Let's use option A, 25 and 36.

Now, the square root of 25 is 5, and the square root of 36 is 6.

So, if we add the square roots together, we get 5 + 6 which equals 11. Now, we don't have the exact square root of 42, but we can clown around and say that it's a pretty close estimate!

So, the answer is A, 25 and 36. Just remember, when estimating square roots, a little laughter goes a long way!

To estimate the square root of 42, we can find two perfect square numbers that are close to 42 on either side.

The options provided are:

A. 25 and 36
B. 36 and 49
C. 49 and 64
D. 25 and 64

We can eliminate options C and D, as 64 is too far away from 42.

Option B is also not accurate, as the square root of 49 is 7, which is too far away from the estimated value of the square root of 42.

The correct answer is option A, as the square root of 25 is 5 and the square root of 36 is 6. These two numbers are closest to 42 and can be used to estimate its square root.

To estimate the square root of a number, you can look for the perfect square numbers that are closest to the given number. In this case, you're looking for two perfect square numbers that are close to 42.

Let's go through the options:

A. 25 and 36: Out of these two, 36 is closer to 42.

B. 36 and 49: 49 is farther away from 42, so this option can be excluded.

C. 49 and 64: Again, 49 is farther away from 42, so this option can also be excluded.

D. 25 and 64: 25 is closer to 42 than 64.

Therefore, based on the options provided, the two square roots that can be used to estimate 42 are 25 and 36.
