Ok so I’m guessing your finding rate I used to struggle to anyway from x to f what’s fifference well first is 5 seconds is 2 3 is times 2 so 1/2 times itself is one one time two is two and last is not linear
We can use #11 as an ex.
7ab and 4 ab
So we combine 7 and 4 (multiply)
=28
Then combine "a". On both sides they are 2 a"s so it would be a^2 and same for b . b^2
Answer: 28a^2b^2.
