2 root 4 = 2 x 2; -2 to the power 4 is 16 (-2/4/-8/16)
If x is a multiplication symbol, then square root of 36(4)y^2 = square root of(4^2)(2^2)(y^2) = (4)(2)(y) = 8y If it is a variable x, then square root of 36x4y^2 = square root of (4^2)(x)(2^2)(y^2) = (4)(2)(y)(square root of x)= 8y(square root of x)
You can take out the perfect square 4: root(40) = root(4 x 10) = root(4) x root(10) = 2 root(10).
4
The square root of -4 is 2i: 2i x 2i = 4i2 = 4(-1) = -4
x plus the square root of 2
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?).
43 * 24 * 7 * 4 * 22 * 72 . 64 * 16 * 7 * 4 * 4 * 49 = 5619712
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
It is: 22 = 4
43 + 42 = 64 + 16 = 80
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?
The cubed root of 43 is 4!The cubed root of 8 (or 23) is 2
PLUS 2
It is the same as the square root of 4 so it is 2
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.
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.

8 divided by 2 = 4 4 to the second power (42) = 16 The square root of 16 = 4
