Square root of 48 equals the square root of 16 times 3; square root of 16 is 4. so one forth times 4(sq root 3) equals the sq root of 3.
The same way as you find the square root with an even-numbered exponent. For example, the square root of x10 is x5. That is, divide the exponent by 2. Similarly, the square root of x7 is x3.5. Once again, you simply calculate one-half of the exponent. If you prefer to express this with integer exponents and square roots, in this example you can write x3.5 as x3x0.5. The second part, x0.5, is equivalent to the square root of "x".
Take the logarithm of 500, half it, then take the antilog.
