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.
For a better understanding of the solution provided here please find the relevant diagram drawn as per given information in the file attached.
As given, 
. Also, it is given that 
is a straight angle. Therefore, 
.
As can be clearly seen from the diagram, if and , then:
Therefore, 
Hence Proved.
Answer:
You haven't provided expressions, so I can work out the problem for you. When we divide fractions, remember always "keep, switch, flip!" That's what we're gonna do here. We keep the 2/5, switch the sign to multiplication, and flip the 7/8 to 8/7. Therefore, we have 2/5*8/7. That gives us 16/35. Hope this helps!

Answer:
The answer is C.
Step-by-step explanation:
The formula to find equation is y - y1 = m(x - x1).
Let (x1,y1) be (6,2) and m is -5/7.
So the equation is,
y - 2 = -5/7(x - 6)
