js 数学 function 为 y√(x)？

Question

³ √(9) = 2.0800838231, or ^Y √x

is there any Math function in vanilla js for calculation above the formula?

Answer 1

Can you try this:

 console.log(Math.pow(9, 1/3)); // replace "3" with the root // "9" with your number

Answer 2

This is what i think will work:

 document.write(Math.pow(9, 1 / 3));

pow raises the second argument to the power of first argument.

Now from basic math we know 3√(9) = (9)^(1/3)

Answer 3

The Math.cbrt() function returns the cube root of a number.

Math.cbrt(x) returns y where x is a number and y * y * y = x.

For example, cube root of 27 = 3, cube root of 8 = 2.

Math.cbrt(27) = 3. Here x = 27 and y = 3. So, y * y * y = x. So, 3 * 3 * 3 = 27.

 console.log(Math.cbrt(8),2); console.log(Math.cbrt(27),3); console.log(Math.cbrt(9),2.080083823051904);
