To avoid multiplying the two numbers and then finding the cube root, find the cube root of each number first. the cube root of 27 is 3x3x3, so you can take out the three to outside of the sqrt, to get 3 cube root 18. eighteen does not have a cube root, so that's all you have to do. the answer would be 3 (cube root) 18.
First simplify the equation of parabola in the following way: . You can see that if x=1 or x=2, then y=0. Two points of intersection with x-axis are (1,0) and (2,0).
in the following way:
.
