Bài 1: Tìm x, biết:
a. { [ ( 2 : x + 14 ) : 22 - 3 ] : 2 } - 1 = 0
b. 10 - { [ ( x : 3 + 17 ) : 10 + 3 . 16 ] : 10 } = 5
Bài 2: So sánh:
a. 1619 với 825
b. 2711 với 818
\(\frac{3}{\left(x+2\right).\left(x+5\right)}\) +\(\frac{5}{\left(x+5\right).\left(x+10\right)}\) + \(\frac{7}{\left(x+10\right).\left(x+5\right)}\)= \(\frac{x}{\left(x+2\right).\left(x+17\right)}\)
