Is i^2 a real number? True or False?Is f(x) = √2, a constant function or a radical function?

When I calculate the value of (-1)1/2 the answer is -1but when I do the same thing but with radical √-1 the answer is error ?!!since the radical √ is to the exponent to 1/2 in case of square root... more

for h(x) = ^3 Radical (X^2 + 9) define two functions f(x) and g(x) such that h is the composite of f and g; in other words decompose h into f and g so that h(x)=f(g(x))   -h(x) = (x^2 + 9) is... more

(3sqrt(x^2)y^3)/(x^2)sqrt(y) Rewrite in terms of fractional exponents and simplify

\sqrt{8^3y^5}\sqrt{2^8y}

i found 6x2 √5 , but i cannot find the restrictions? If anyone can help me with this ive been stuck on this question.  Thank you

explian how to do  the cubed root of -125x^4y^6 walk me through it and explain how to get the answer. 

Hi, im having troubling solving : √8-x2 + x=0    ** 8-x2 is all under one radical. The + x is not part of the radical**

Hi, the equation I need help with is : √2x2  — 3x + √2 =0 

solve the equation: the square root of x+2 - the square root of 2x+3 = -1

what are the solutions to the equation: the square root of x+5 + the square root of x-5 = 10

So the problem I have is (x-4)2/3=100. I used the "help me solve this" feature and it gave me:   ((x-4)2/3)3/2=+-(100)3/2   and that gave me:   x-4=+-1000     I know how you got x-4 by... more
