Sorry i'm asking a lot of questions i just dont understand

answer:

d. 3 to the power of 2 multiplied by 1 whole over 4, the whole squared. = 3 to the power of 4 multiplied by 1 squared over 4 squared. = 81 over 16.  

step-by-step explanation:

this is an exercise in pemdas, the order of arithmetic operation:  

parentheses > exponents > multiplication and division > addition and subtraction.  

[(3² × 5⁰)/4]² = [(9 × 1)/4]² = (9/4)² = 81/16  

    3⁴ × 1²/4² = 81 × 1/16                 = 81/16  

a. is wrong. 3¹ × 1²/4² = 3 × 1/16 = 3/16

b. is wrong. [(3² × 0)/4]² = [(9 × 0)/4]² = (0/4)² = 0² = 0  

c. is wrong. [(3² × 0)/4]² = 0

answer:

2.75

step-by-step explanation:

55-11(4)=2.75

2.75+11=13.75

13.75x4=55
