WebThe log () function takes a single argument and returns a value of type float. [Mathematics] log e x = log (x) [In C programming] It is defined in header file. In order to find the log () of long double or float numbers, you can use the following prototype. long double logl ( long double arg); float logf (float arg); WebJun 14, 2024 · Video. Check if a number can be expressed as x^y (x raised to power y) Given a positive integer n, find if it can be expressed as x^y where y > 1 and x > 0. x and y both are integers. Examples : Input: n = 8 Output: true 8 can be expressed as 2^3 Input: n = 49 Output: true 49 can be expressed as 7^2 Input: n = 48 Output: false 48 can't be ...
