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.

When you see "y times 2," it means you are multiplying the variable y by the number 2. So the expression "y times 2" can be written as 2y. This is a simple algebraic expression where the coefficient of y is 2.
Well, isn't that just a happy little math problem we have here! To multiply 2x by 2y, you simply multiply the numbers together: 2 * 2 = 4. And then you multiply the variables together: x * y = xy. So, the result is 4xy. Just like that, you've created a beautiful mathematical expression!

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.

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.
