Por favor me ajudem!!

Answer 1

Resposta:

A) 11a + 11b = 22ab

( 11 + 11 = 22 ) + ( a + b = ab ) = 22 + a . b = 22ab

B) 3ax + 3bx = 6axb

( 3 + 3 = 6 ) + ( ax + bx = axb ) = 6 + a . x . b = 6axb

C) 2b + 2c + 2d = 6bcd

( 2 + 2 + 2 = 6 ) + ( b + c + d = bcd ) = 6 + b . c . d = 6bcd

Resposta A: 22ab

Resposta B: 6axb

Resposta C: 6bcd.
