Answer 1

I don't really know how to do this but the best thing I can say is to replace those variables with a number and then put it in a calculator. Make sure each variable has a different number.

so for the first one, I made s as 2 and t as 3. I got 18 for the first one and 6 on the other one so they're clearly not equal.

good luck!
