Answer 1

B= (7^2 +1) ÷ (1+4)^2 • (2^3 -3)

*7^2 = 7•7= 49*

(49+1) ÷ (1+4)^2 • (2^3 -3)

(50) ÷ (1+4)^2 •(2^3 -3)
50÷ (1+4)^2 •(2^3 -3)
50÷ (5)^2 • (2^3 -3)

*(5)^2 = 5^2= 5•5 = 25*

50 ÷25 • (2^3 -3)

*2^3 = 2•2•2=8*

50÷25 • (8 -3)
50÷25 • (5)
50÷25 • 5
2 • 5
10


C= 9^2 ÷ (7^2+1-23)

*9^2= 9•9 =81*

81 ÷ (7^2 + 1 -23)

*7^2 = 7•7 = 49*

81 ÷ (49 +1 -23)
81 ÷ (50 -23)
81 ÷ (27)
81÷27
