y5 * y3 * y = y5 * y3 * y1 = y5+3+1 = y9
y^8
x squared times y to the negative four thirds power
13
1.2
y times y times y (or y3)
y^9
y*x8
x to the 5th power times y to the fourth power
(y6) (y5) = y11
y to the 36 power
y to the 36 power
It is 1/y5
y4
8 = 2 x 2 x 2 (the x's are as multiplication signs) or 23 which is 2 to the 3rd power
x squared times y to the negative four thirds power

Find out what y is and times by fourteen
(x + y)3 + (x - y)3 = (x3 + 3x2y + 3xy2 + y3) + (x3 - 3x2y + 3xy2 - y3) = 2x3 + 6xy2 = 2x*(x2 + 3y2)
