(9) · (x) · (2/3) · (y) = 6 x y

When multiplying powers, you add them! y4 times y6 = y10. Try it with y = 2: 2 to the fourth = 16, 2 to the sixth = 64 16 x 64 = 1024 = 2 to the tenth.
To find 2 times the sum of x and y, you first need to calculate the sum of x and y by adding the two variables together. Once you have the sum, you multiply it by 2 to get the final result. In mathematical terms, the expression for 2 times the sum of x and y can be written as 2(x + y).
It is: 2*(x+y) or 2x+2y
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.

suppose u have a(x) and b(y)where a and b are constants , Multiplying a(x) by b(y) it's simply ab(xy) So if u have 2x by 2y this equals to 4xy or The answer is 4xy. 2x = 2 times x 2y = 2 times y 2 times x times 2 times y = 2 times 2 times x times y = 4xy

2(y + 5)
yes * * * * * No, it isn't. 2xy = 2 times x times y. Depending on which you mean: 2x2y = 2 times x times 2 times y = 4xy; OR 2x2y = 2 times x times x times y.

y=(2x)2 y=2(2x) y=4x
2 times 2 times 5 times x times y
When multiplying powers, you add them! y4 times y6 = y10. Try it with y = 2: 2 to the fourth = 16, 2 to the sixth = 64 16 x 64 = 1024 = 2 to the tenth.
2 times 2 times 2 times x times y equals 8xy
