7 |7
1 |2²X2²X7

√112 = 4√7

175|5
35 |5
7 |7
1 |5²X7

√175 = 5√7

2√7 + 4√7 + 5√7 = 11√7
COMO FAZ ISSO???

Answer 1

\/28 = \/4 x \/7 = 2\/7
\/112 = \/16 x \/7 = 4\/7
\/175 = \/25 x \/7 = 5\/7

\/28+\/112+\/175 = 2\/7+4\/7+5\/7 = (2+4+5)\/7 = 11\/7

Answer 2

Resposta:

\/28 = \/4 x \/7 = 2\/7

\/112 = \/16 x \/7 = 4\/7

\/175 = \/25 x \/7 = 5\/7

\/28+\/112+\/175 = 2\/7+4\/7+5\/7 = (2+4+5)\/7 = 11\/7
