Need some help simplifying please!

I know you have to make the bases the same but I need further help.

Write an equivalent equation to represent c as a function of n by simplifying the expression on the right side of c(n)=0.5(500(1.03)n)

The length of a rectangle is 3 cm more than the width. The area is 70cm2 . Find the dimensions.

I'm very confused about how to separate the variables, and the numbers, or when to move stuff to the outside of the radical.

1/(16^1/2-15^1/2)-1/(15^1/2-14^1/2)+1/(14^1/2-13^1/2)-1/(13^1/2-12^1/2)+1/(12^1/2-11^1/2)-1/(11^1/2-10^1/2)+1/(10^1/2-9^1/2)

2j+6/ j2 -6j-27 i solved the whole thing and ended up with j= 9 (equal sign with a slash through it) but Ive learned there should be another value I'm very stuck on this...

dont get it. / means they are fractions.

I've already simplified this from -4 plus the square root of 32 over -2 times 5. I'm just a little confused on how to simplify it further, but I know it can be.
