Answer:
a) correct
b) the correct answer is 28
c) the correct answer is 21
d) the correct answer is 26
Step-by-step explanation:
a) using GEMDAS rule and the MDAS rule
3²+(2+12×2)-16÷4= 31
(GEMDAS rule, first to solve is 2+12×2 = 26)
3²+26-16÷4
(MDAS rule, there's nothing to multiply(M) so proceed to division (D) which is 16÷4 = 4)
3²+26-4
(MDAS rule, proceed to addition but there's an exponent so u must first multiply the 3 to itself(3×3) equal to 9,then proceed to addition 9+26=35)
35-4= 31
