Given the formula X =a(m2 – n2), find the X when a = 5, m = 11 and n = 9.
Question
Given the formula X =a(m2 – n2), find the X when a = 5, m = 11 and n = 9.
Solution
Sure, let's solve the equation step by step.
First, we need to calculate the value of m^2 - n^2.
Given m = 11 and n = 9,
m^2 = 11^2 = 121 and n^2 = 9^2 = 81.
So, m^2 - n^2 = 121 - 81 = 40.
The formula is X = a(m^2 - n^2). We are given a = 5.
Substitute the values into the formula, we get X = 5
