To find the nth root of a number in PHP, we can use the pow(base, power)<\/code> function, for example the cube root of 27 is equal to 27 raised to the power of 1\/3, \\(\\sqrt[3]{27} = 27^{1\/3}\\), since \\(3^3=27\\). In general the nth root of x, \\(\\sqrt[n]{x}=x^{1\/n}\\).<\/p>\n

To calculate the square root of a number, we can also use the sqrt(number)<\/code> function.<\/p>\n

Example<\/h2>\n

Some example code showing how to calculate roots in PHP is below:<\/p>\n

<?php\r\n\/\/ Square root\r\necho sqrt(49) . \"<br \/>\";  \/\/ square root of 49\r\necho pow(49,1\/2) . \"<br \/>\"; \/\/ alternative to square root of 49\r\necho pow(8,1\/2). \"<br \/>\"; \/\/ square root of 8\r\n\r\n\/\/ cube root\r\necho pow(8,1\/3). \"<br \/>\"; \/\/ cube root of 8\r\necho pow(27,1\/3). \"<br \/>\"; \/\/ cube root of 27\r\n\r\n\/\/ higher roots\r\necho pow(390625,1\/4). \"<br \/>\";\r\necho \"25^4 = \" . pow(25,4) . \"<br \/>\";\r\n\r\necho pow(1234, 1\/6). \"<br \/>\";\r\n?><\/pre>\n
The output from this example is as follows:<\/p>\n
7\r\n7\r\n2.8284271247462\r\n2\r\n3\r\n25\r\n25^4 = 390625\r\n3.2750594908837<\/pre>\n
You can also use the pow()<\/code> function in PHP to raise one number to the power of another (i.e. take the exponent). We cover this in a separate guide: Raise a Number to the Power of Another in PHP<\/a>.<\/p>\n\n","protected":false},"excerpt":{"rendered":"
