Answer 8

Remember PEMDAS?

First square the 5.
3*25-2

then multiply

75-2

then subtract
73

Answer 9

i thought you would do the exponents 3a*3a=9a plug in a so 9*5=45-2=43

Answer 10

No, the equation is 3a^2-2

You're given a=5 so just put that into the equation where a is.
3(5)^2-2

and that gives you 73
