Bonjour,

A = 8/3 + 5 : (1 - 2/5)
A = 8/3 + 5 : (5/5 - 2/5)
A = 8/3 + 5 : (3/5)
A = 8/3 + 5 x 5/3
A = 8/3 + 25/3
A = 33/3
$\boxed{A = 11}$

B = (55 x 10^3 x 2^10) / (10^4 x 2^9)
B = 55 x [10^(3-4)] x [2^(10-9)]
B = 55 x 10^(-1) x 2^1
B = 110 x 10^(-1)
B = 11 x 10^(1-1)
$\boxed{B = 11}$

Donc :
$\boxed{A = B}$
