Yx7y = 7y2 (squared )
18
x to the 5th power times y to the fourth power
6(4+y)
3y
y to the 36 power
y times y times y (or y3)
y times y times y
I assume you mean 2 times y times y times y. Since y is multiplied by itself three times, you have 2 times y3, also known as 2 times y cubed, which is written as 2y3.
W goes into Y: y ÷ W = Y/W times.
-3 times 4 times y = -12y
y/5
It is: x times y or as xy
5 times y is the same as 5y in algebra
W goes into Y: y ÷ W = Y/W times.
5 times 17 times x times x times y times y = 85x2y2
That would be Y2 or Y squared.
