Question 90

$$\frac{28 \times 5-14 \times 4}{8^{2}+\sqrt{225}+(14)^{2}}=?$$

Solution

We need to find the value of $$\frac{28 \times 5-14 \times 4}{8^{2}+\sqrt{225}+(14)^{2}}$$

Let us find the value of the numerator first $$28 \times 5 - 14 \times 4 = 140 - 56 = 84$$
And the value of the denominator equals $$8^2 \sqrt{225} +14^2 = 64 + 15 + 196 = 275$$

Hence, the value of the fraction is $$\frac{84}{275}$$

Hence, the correct answer is option (b)
