đặt \(\sqrt[5]{\frac{16x}{x-1}}=a\)

=> \(\sqrt[5]{\frac{x-1}{16x}}=\frac{1}{a}\)

ta duoc: a+1/a=5/2

tự giải tiếp nhé

Bạn có thể giải giúp mik đc ko?

Gọi số cần tìm là abc

8abc - abc8 = 5778

=> c = 6

=> b = 4

=> a = 2

Vậy số cần tìm là 246

1+1-1+1-1+1-1+1

=2-1+1-1+1-1+1

=1+1-1+1-1+1

=2-1+1-1+1

=1+1-1+1

=2-1+1

=1+1

=> =2

Và Bố+Mẹ=2 thì có thể Bố bằng 0; Mẹ bằng 2 hoặc Bố bằng 1; Mẹ bằng 1 hoặc Bố bằng 2; Mẹ bằng 0

đáp số là 325
