Question

Is the following expression shown the exact answer? 144π - 216√3

true or false

Answer 1

`144\pi - 216√(3) \\\\ 144 = 2^4 * 3^2\\\\ 216 = 2^3 * 3^3\\\\ \Longrightarrow~~\text{Common factor } = 2^3 * 3^2 = 8 * 9 = 72\\\\ \Longrightarrow~~ 144\pi - 216√(3) = \boxed{72\Big(2\pi - 3√(3) \Big)}`
