Soluções para a tarefa
Respondido por
11
a) 8/x + 1/2x
16/2x + 1/2x = 17/2x
b) 3a/1 - 2/3a
3a²/3a - 2/3a = (3a²-2)/3a
c) 1/2x + 1/3x
3/6x + 2/6x = 5/6x
d) 2/3x² - 1/2x²
4/6x² - 3/6x² = 1/6x²
e) 1/2y - 2/5y
5/10y - 4/10y = 1/10y
f) 2x/2x - 3/4x
4x/4x - 3 / 4x = ( 4x-3)/4x ok
16/2x + 1/2x = 17/2x
b) 3a/1 - 2/3a
3a²/3a - 2/3a = (3a²-2)/3a
c) 1/2x + 1/3x
3/6x + 2/6x = 5/6x
d) 2/3x² - 1/2x²
4/6x² - 3/6x² = 1/6x²
e) 1/2y - 2/5y
5/10y - 4/10y = 1/10y
f) 2x/2x - 3/4x
4x/4x - 3 / 4x = ( 4x-3)/4x ok
