Question

The approximate value of$\sqrt{{\left(1.97\right)}^2{\left(4.02\right)}^2{\left(3.98\right)}^2}$

• A. $31.59$
• B. $5.099$
• C. $5.009$
• D. $5.734$

Answer 1

The correct option is A $31.59$

We have,

$\sqrt{{\left(1.97\right)}^2{\left(4.02\right)}^2{\left(3.98\right)}^2}$

$=1.97\times 4.02\times 3.98$

$=31.59$

Hence, this is the answer.
