Question

Am nevoie de ajutor urgent va rog!
Calculează:
B=[11,2(3)-9,(2)]*9-1 supra 100=

Answer 1

B=[11,2(3)-9,(2)] × 9 - 1/100

11,2(3) = (1123 - 112)/90 = 1011/90

9,(2) = (92 - 9)/9 = 83/9

B = ( 1011/90 - 83/9) × 9 - 1/100

B = (1011/90 - 10×83/90) × 9 - 1/100

B = (1011/90 - 830/90) × 9 - 1/100

B = 181/90 × 9 - 1/100

B = 181/10 - 1/100

B = 10 × 181/100 - 1/100

B =( 1810 - 1)/100

B = 1809/100

B = 18,09

Answer 2

11,2 ( 3 ) = ( 1123 - 112 ) / 90 = 1011 / 90

9, ( 2) = ( 92 - 9 ) / 9 = 83 / 9

B = ( 1011 / 90 - 83 / 9 ) × 9 - 1 / 100

B = ( 1011 - 830 ) / 90  × 9 - 1 / 100

B = 181 / 10 - 1 / 100

B = 1810 / 100 - 1 / 100

B = 1809 / 100

B = 18,09
