work out an estimate for square root of 4.92+2.18*7.31

Answer: Our estimated value would be 5.

Step-by-step explanation:

Since we have given that

[tex]4.92+2.18\times 7.31[/tex]

First we need to multiply 2.18 and 7.31.

We get

[tex]2.18\times 7.31=15.9358[/tex]

Then it add to 4.92 to get

[tex]15.9358+4.92\\\\=20.8558[/tex]

So, the square root of 20.8558 would be

[tex]\sqrt{20.8558}=4.56[/tex]

Hence, our estimated value would be 5.
