Bạn đi học rồi hả

1x2x3x..x9-1x2x3x..x8-1x2x3x..x82

(3x4x216)2 / 11x213 x411 -169

13-12+11+10-9+8-7-6+5-4+3+2-1

A=666..66(100 chữ số 6)x999..99(100 chữ số 9)

Mình cần gấp giúp mình nha!

Đọc tiếp...

tự làm đi bạn dễ mà

\(=\dfrac{3^2\cdot2^{36}}{11\cdot2^{13}\cdot2^{22}-2^{36}}=\dfrac{3^2\cdot2^{36}}{2^{35}\cdot9}=2\)

\(=\frac{3^2.4^2.2^{32}}{11.2^{35}-2^{36}}\)

\(=\frac{3^2.4^2.2^{32}}{2^{35}\left(11-2\right)}\)

\(=\frac{3^2.4^2.2^{32}}{2^{35}.3^2}\)

\(=\frac{4^2}{2^3}\)

\(=\frac{2^4}{2^3}\)

\(=2\)
