Problem 1: Divide and simplify d^7/d^13
2 a). solve 5x^2=15
b). find the x-intercepts of f(x)=5x^2-15
3. Simplify by taking roots of the numerator and the denominator. Assume that all expressions under radicals represent positive: 3sqrt216x^8/y^3
4. Multiply and simplify. Assume variables represent nonzero real numbers: y^15 y^0
5. Subtract and simplify by collecting like radical terms if possible if possible: 7sqrt32-7sqrt2
6. In a right triangle find the length of the side not given b=2, c=sqrt13 the length of the third side is ?
7. Use the foil method to find the product: (8x^3-9)(x^9-3)
