Instructions
What approximate value should come in place of the question mark (?) in the following questions? You are not expected to calculate the exact value.
Solution
In order to find the approximate value of $$9.5^2$$, we write $$9.5 = 9 + 0.5$$
So, $$9.5^2 = (9+0.5)^2 = 9^2 + 2*0.5*9 + 0.5^2 = 81 + 9 +0.25 = 90.25 \approx 90$$
