What is 4 square root of 10?

Answer: 4×4×4×4×4×4×4×4×4×4 =1048576 Answer: There is no "4 square root of 10". There is a square root (which number must I square - i.e., raise to the power 2 - to get 10?) and there is a 4th. root (which number must I raise to the 4th. power to get 10?).

How do you raise a number to the power of a half?

Take its square root. All fractional exponents indicate roots. For example, the power 22 = 4, so sq rt 4 = (4)½ = (22)½ = (2)1 = 2

Why can't you simplify the square root of x to the power of 2 plus 4?

ok lets let x=4. The square root of 4 to the 2nd power + 4= 8. The square root and power of 2 cancel out? Is that what you mean?

How do solve a composite function that is a radical inside of a radical?

By radical, I am assuming that you mean square root, not cube root, quartic root, or otherwise. If this is the case, then we can use fractional exponents to help. Change sqrt(x) to x^(1/2), or x to the one half power. Then we take a radical of a radical which becomes sqrt(x^(1/2)) = (x^(1/2))^(1/2) = x^(1/4). When we raise a power to a power, we multiply exponents. So the answer to the square root of the square root of x is x to the one fourth power, or the 4th root of x.


What does a fraction in an exponent do?

The fraction in an exponent takes the base to that radical power (1/2 is take the square root, 1/3 is take the third or "cube" root, 1/5 is take the fifth root, etc) and the numerator to that positive power (2 is squared, 3 is cubed, etc) For example: 4 to the 1/2 power is the square root of 4, which is two. 4 to the 3/2 power is the square root of four, 2, taken to the third power, which is 8.
