Answer:
The third option: -24
Step-by-step explanation:
21 + [tex]6^{2}[/tex] - ( 35 - 8 ) · 3
So you need to solve this according to BEDMAS / PEMDAS (same thing)
Brackets/Parentheses, Exponents, Division/Multiplication, Addition/Subtraction.
Btw, don't worry about ( · ), it means multiplication ( × )
So according to BEDMAS / PEMDAS...
= 21 + [tex]6^{2}[/tex] - ( 35 - 8 ) · 3
= 21 + [tex]6^{2}[/tex] - 27 · 3
= 21 + 36 - 27 · 3
= 21 + 36 - 81
= 57 - 81
= -24
