Find out the approximate value which should replace the question mark in the following questions (you are not expected to find out the exact value)

Question 121

$$95^{3.7}\div95^{0.9989}=95^{?}$$

Solution

We know that $$x^a \div x^b = x^{a-b}$$

Using that formula in the expression given, $$95^{3.7} \div 95^{0.9989}= 95^{3.7-0.9989}$$
This equals $$95^{2.7011} \approx 95 ^{2.7}$$
