Oh this can be done EASILY!! ^-^* Okay Start off by plugging in the given values into the equation....

Answer 2

just plug the given values in the places of the corresponding variables

Answer 3

i don't know what that means

Answer 4

19 + 5(2)^4 - 3(-4)^2

plugging in values means to put the numbers given for the variables into your equation like I've done above....

Answer 5

In place of a plug 2 and in place of b plug -4\[19 + 5 (2)^4 - 3 (-4) ^2\]

Answer 6

oh ok

Answer 7

i've done that now

Answer 8

alright now, step by step.. you have to solve in order so think of PEMDAS.. start with parentheses... sooo 5 x 2 = 10.. then 10 x 10 = 100 that part is solved..

now your equation should look like: 19 + 100 - 3(-4)^2

Answer 9

okay i'm writing this down

Answer 10

Oops i made a MISTAKE!!!.... it's supposed to be 10 x 10 x 10 because it's to the third power.. sooo its supposed to be 19 + 1000 - 3(-4)^2

Answer 11

sorry /.< okay next..

Answer 12

oh. ok

Answer 13

same with the other parenthesis.. 3 x -4 = -12.. then -12 x -12 (because here it's squared) = a POSITIVE 144...

NOW your equation should look like: 19 + 1000 + 144... Add'em up and i think you have your answer c:

Answer 14
