(y6) (y5) = y11
y*x8
x to the 5th power times y to the fourth power
y5 * y3 * y = y5 * y3 * y1 = y5+3+1 = y9

y^6
When you multiply two terms with the same base, you add their exponents. In this case, y to the power of 4 multiplied by y to the power of 5 is equal to y to the power of (4+5), which simplifies to y to the power of 9.

This is definitely false; if x=2 and y=3, x to the y power is 8, but y to the x power is 9, which are not equal.
