y cubed times y to the fourth power is y to the seventh, since 3 plus 4 is 7.

So let's try some examples.

Transform 5x cubed y to the fourth times 7x squared y to the eighth.

And then 3xy squared times 5x cubed y.

And also 4x to the fourth y to the ninth of 3 times 5x to the third y to the ninth of fifth.
