Question

Como faz a soma do perimetro com as raizes : raiz de 112, raiz de 28 e raiz de 175 

Answer 1

\/112 + \/28 + \/175 = 
Precisamos decompor os números:
112|2..............28|2....................................175|5
056|2..............14|2......................................35|5
028|2..............07|7......................................07|7
014|2..............01.........................................01
007|7...............28 = 2^2x7...........................\/175 = \/5^2 x 7
001..................\/28 = \/2^2x7......................\/175 = 5\/7
112 = 2^4 x 7......\/28 = 2\/7
\/112 = \/2^4 x 7 
\/112 = 2².\/7 = 4\/7

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