Question 1037462: Simplify: 3 sqrt 75 ÷ sqrt 27
Here's how I tried to solve it:
3 sqrt 75 ÷ sqrt 27
3 sqrt 25*3 ÷ sqrt 9*3
3*5 sqrt 3 ÷ 3 sqrt 3
15 sqrt 3 ÷ 3 sqrt 3 I then cancel out the 3 radicals to get:
15/3
15/3= 5 (the answer I thought was correct)
I check the answer key,
the correct answer is 25/3.
I'm having trouble figuring out how that could be the answer. I feel like I probably went wrong when I cancelled the radicals.

Question 1038459: In 1997, there were 43.2 million people who used free weights. Assuming the use of free weights increases 6% annually, which equation can be used to predict the number of people using free weights t years from 1997?
p = 43.2(0.06)^t
p = 43.2(1.06)^t
p = 43.2(0.94)^t
p = 43.2(1.005)^t
