<span>(243)^(2/5) = ?
---
The 5 in the denominator means "take the 5th root".
The 2 in the numerator means "square".

</span><span>Taking the 5th root first you get:
(243)^(2/5) = 3^2
Now squaring gives you
3^2 = 9
So the answer is 9.
Hope this helps :)

The product means you multiply, so:
-y × 6x = -6xy
-y × 4y = -4y²
x × 6x = 6x²
x × 4y = 4xy
= -2xy - 4y² + 6x
I hope this helps!
Use distance formula:-
distance = sqrt [ (x2 - x1)^2 + (y2 - y1)^2) ]
let (x1,y1) = (-3,1) and (x2,y2) = (-1,6) Plug these values in to formula.
