What is 3 times 3? what is f5 times 5? what is 9189 dived by 3 times 7 squared?

So 3 times 3 means 9 (times tables) or
 3 of 3 or 3+3+3 or 9

so f5 times 5 means (f)(5)(5) associative property of multiplication says (ab)c=a(bc) so
(f)(5)(5)=f25 or 25f

9189 divided by 3 times 7^2
pemdas
parenthasees exponents mult/division whicherver comes first, addition/subtraction whicherver comes first

so 7^2 is first
7^2=7 times 7=49 (times tables)

then division
9189/3=3063

then 3063 times 49= (use calculator) 150,087

Aand b is what i think
