We need to find the value of $$frac{28 imes 5-14 imes 4}{8^{2}+sqrt{225}+(14)^{2}}$$ Let us find the value of the numerator first $$28 imes 5 - 14 imes 4 = 140 - 56 = 84$$
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)
