Question

Estimate each square root or cube root to the nearest integer.

pls answer this paper is due in an hour.

Answer 1

2. is 7 3. is 4

Explanation:

Here's how yo do these. I'll do one of the square roots for you and one of the cube roots, then you'll be able to do the other two.

First you have to understand that square root means "What number multiplied by itself gives me this number?" That's the key, memorize it.

For cube roots it's, "What number multiplied by itself 3 times?"

So knowing that, let's work on
`√(55)`.

What number multiplied by itself gets you close to 55?

• You should recognize that 7 x 7 = 49, so that's close.
• But now try 8: 8 x 8 = 64. That's close too.
• Which one is closer? 49, right?

So the answer "to the nearest integer" is 7.

Now let's find the cube root of 70:

• Maybe start with 4: 4 x 4 x 4 = 64. Pretty close.
• But try 5: 5 x 5 x 5 = 125. Waaaay too far away.

So the answer is 4.
