(2--3)2 + 2(-3)3

(5)2 + (-6)3

25 + -216

-191 either im wrong somewhere or my book doesnt have that answer my choices are -29,43,79,-53

I am assuming that by 2(-3)3 you mean

2(-3)

you did not follow the order of operation which says exponents before multiplying

that part should then be

2(-27)

so your last line is

25 + (-54)

= -29
