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
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.
2 times 2 times 3 times 3 times x times x times y
2 *5y
3y2 y x y = y2 3 x y2 = 3y2
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.

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.
(9) · (x) · (2/3) · (y) = 6 x y
y4
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
