How would you do these maths questions?

1. Simplify - 8x^4y^5 divided by 4xy^2

2. If the area is 250, what is the diameter?

1. I think the answer is 2x^3y^3
2. What is the question? What are the length of the sides? Cause there are multiple factors that go into 250.

The question is the area of a circle is 250cm^3 what is the diameter of the circle?
Well, you divide 250 by pi which gives you the radius squared. Square root r^2 (this means radius squared) to give you the radius. Double the radius to get the diameter.

Oh yes, I am very aware of how great of a saviour I am. The constant mails I receive thanking me is starting to get rather exasperating...

The origin of all existing greatness in this vast universe is Wolfram Alpha. It seems you are not aware of who is behind ExamSolutions... :wink:
