Question 134716: I am having so much trouble with this question. I will show you the original question and then will show what I have. Please complete the problem for me from start to finish so that I am no longer as confused as I am now. This is what I have:
(3x)^-1/3=
3^-1/3 * x^-1/3=
1/3^1/3 * 1/x^-1/3=
3^1/3= 3cubert3=
1/3cubert3x
I am not allowed to leave radicals in the denominator, I am completely confused, can you please solve the original? The original problem again is (3x)^-1/3

Question 135290: This is the question I'm having problems with...
Suppose P dollars in principal is invested in an account that earns interest annually. If after t years the investment grows to A dollars, then the annual rate of return, r, on the investment is given by
r = A/P^1/t -1
Find the annual rate of return on $7,000 which grew to $12,200 after 5 years.
Round your answer to one decimal place.
I filled in the equation with:
r= 12200/7000^1/5 -1
I cancelled out the zeros to get r=122/70^1/5 -1
I'm unsure where to go from here. Thanks.

Question 135302: Please show me how to solve this equation. w= Cr-2 for r. C is the constant and r is the distance that the object is from the center of the earth. 100 pounds when at sea level 3,963 miles from the center of the earth. this is not from a textbook it was an appendix assignment from intermidiate algebra class 117.
