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
