Evaluate $\sqrt{\frac{9.5 \times .0085 \times 18.9}{.0017 \times 1.9 \times 0.021}}$

Answer:

Explanation:

Given exp. = $\sqrt{\frac{9.5 \times .0085 \times 18.9}{.0017 \times 1.9 \times 0.021}}$
Now, since the sum of decimal places in the numerator and denominator under the radical sign is the same, we remove the decimal.
Given exp. $=\sqrt{\frac{9.5 \times .0085 \times 18.9}{.0017 \times 1.9 \times 0.021}}$
$=\sqrt{5\times 5\times 900}= 5\times 30 =150$
