Question 82463: Hello, this question isn't from a book. It is a paper assignment. Please help I am confused with this.
Is the square root symbol with an x^2 power under it=x an identity (true for all values of x)? Sorry I wasn't sure how to put the square root symbol in. I hope you can understand what I am asking. If at all possible to help me before Saturday by 8:00 pm central time I would really appreciate it. Thank you.

Question 82536: Please help me with the following problem.
A right triangle is a triangle with one angle measuring 90°. In a right triangle, the lengths of the sides are related by the Pythagorean Theorem, c²= a²+ b² where c is the length of the hypotenuse (the side opposite the 90° angle). Find the length of the hypotenuse when the other two sides’ measurements are 3 feet and 4 feet.
thank you for your assistance.

Question 82583: If P is power (in watts) and R is resistance (in ohms), then the voltage V necessary to run the circuit is V=√PR
Find the voltage necessary to run a 40-watt amplifier with a resistance of 150 ohms.
Okay I set the problem up and did the work. Did I get it right?
V=√40*150
V=√77.45966
V=38.72983

Question 82539: Please help me solve the following question...I'm so confused!
While the radical symbol is widely used, converting to rational exponents has advantages. Explain an advantage of rational exponents over the radical sign. Include in your answer an example of an equation easier to solve as a rational exponent rather then a radical sign.
thank you for your help.

Question 82725: This problem is not from a textbook.
I apologize for writing this all out in words. I don't know how to get the radical sign to appear here. ( I will try to also put this in symbol form by using a capital 'V' to stand for the radical)
3 times the square root of 5/12 plus the square root of 12/5 - 1/3 times the square root of 60.
3 V5/12 + V12/5 - 1/3 V60

Question 82751: I am not sure if I am doing everything I need to do in this equation.
Here it is:
Simplify. Write your answer in radical form. Assume that x is a positive real number.
The square root of 3/2x(three over 2x) multiplied by the square root of 8x^3/6 (eight x cubed over 6).

Question 83153: Can you help me answer this question?
radical sign and the radicand under it is x to the 3rd power = 8.
I don't know how to answer it, but I think the answer is x = 4, but I don't know how I came to that conclusion.

Question 83152: Radical sign and the radicand under it is x - 1 = 3
This is what I got. Let me know, if it is correct.
radical sign and the radicand under it is x - 1 = 3
+ 1 +1
x = 4
radical sign and the radicand under it is x squared = (4) squared
answer = x = 16

Question 83261: Hello! I am unsure how to solve this.
(2(sq5a)-3(sq4b))2nd power= In words it is (2 times the square root of 5a minus 3 times the square root of 4b) all to the second power
I got 20a - 36b is this correct?
Thank You!

Question 83300: am so behind in my math homework. I need help.
The volume of a cylinder (think about the volume of a can) is given by V = pie symbol r squared h where r is the radius of the cylinder and h is the height of the cylinder. Suppose the volume of the can is 100 cubic centimeters.
Write h as a function of r. Keep pie sign in the function’s equation.
What is the measurement of the height if the radius of the cylinder is 2 centimeters? Round your answers to the nearest whole number.
Graph this function.
