1)Simplify:(6x^316x^2+11x5)/(3x2)
answer= 2x^24x+13over3x2
2)Factor 27x^31 completley.
answer= (3x1)^3 if this isnt correct,im not sure how to solve it b/c this makes the most sense to me.
3)Simplify: x^23x28 over x^29x+14,assume that the denominator is not equal to 0.
answer= x+4 over x2
4)Simplify: square root of 64n^6w^4
answer= 8n^3w^2
5)Simplify: (3 is on the point of the square root sign,not on top of 625) square root of 625x^5
answer= 25x^2
3 is correct.
4 is correct.
If you are trying to get cuberoot 625x^5
then rewrite it as
cubroot (5^4 * x^5)
cuberoot(5*5^3*x^3*x^3)
then pull the perfect cubes out.
