bonsoir ki pourrai m aider svp ​

bonjour

A = ( 5/2 x 3 /4 + 1 ) :  ( 1/10 + 7/5 )

A = (  15/8 + 1 ) :  ( 1/10 + 14/10 )

A = (  15/8 + 8/8 ) :  15 /10

A = 23/8 x 10/15

A =  230/120

A = 23/12

A =  23/12 = 1.917

B = ( 2 ² + 7 035 ⁰ )³ - ( 2 ⁴ + 7.5 )²

B =  ( 2 ⁶ + 7 035 ⁰) - ( 2 ⁸ + 7.5 ² )

B =   (64 + 1 ) - ( 256 + 56.25 )

B = 65 - 312.25

B = - 247.25

B = - 2.4725 * 10 ²
