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.
