\(A=\frac{2^{2015+1}}{2^{2015}-1}=1+\frac{2}{2^{2015}-1}\)

Sau 3 năm nữa, mẹ vẫn hơn con 27 tuổi và gấp 4 lần tuổi con. Nếu tuổi con là 1 phần thì tuổi mẹ là 4 phần. 
Hiệu số phần bằng nhau là: 4 - 1 = 3 
Tuổi mẹ sau 3 năm là: 27 : 3 x 4 = 36 (tuổi) 
Tuổi mẹ hiện nay là: 36 - 3 = 33 (tuổi) 
Tuổi con hiện nay là: 33 - 27 = 6 (tuổi) 
Đáp số: Mẹ: 33 tuổi; Con: 6 tuổi.

đúng cái nha
