    Basically substitute those numbers for your variables in the equation

    s=7, a=5, m=3, and t=4 \[2a ^{2} + st -3m = 2(5)^{2} + (7)(4) -3(3) = 69\]

    @happyrosy It should be 10^2

    (2a)^2 (2 times 5)^2 10^2

    So 100 + 28 - 9 = 119

    The 2a is in parenthesis… they must be multiplied first.

    You should put parenthesis around whatever you do in the calculator

    You have to solve 5^2 first in 2(5)^2 = 2(25) = 50

    2a isn't in parenthesis. Just a is. So focus on the 5 first and then go for the exponent, which is 2. 5 squared = 25. Multiply that by 2 you get 50

    You gave the problem like (2*5)^2 + 28 - 9

    simply put the number to the alphbet (2a)^2+st-3m s=7 a= 5 m=3 t= 4 y=2^x-1 it should look like this know put it in ur ti 84 calutor (2*5)^2+7*4-3*3.

    Oh okay. So it is actually \[(2a)^2\] not \[2a^2\]
