How to calculate if PHP is raised to the nth power?

PHP has the square root function sqrt(), but now I want to raise the 1.2th power of a number. Is there any good way? Can you only write a function yourself?

Wrong reading=. = , use pow(). Mathematical principles The square root of 25 will be 25 raised to the 1/2 power, so the 1.2 raised power of 25 will be 25 raised to the 1/1.2 power pow(25,1/1.2)

Use the pow() function, for example, 100 raised to the power 1.2 is 100 raised to the power 1/1.2, written as pow(100,1/1.2)

php5.6 uses echo 25**(1/1.2);//14.620088691064
