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...

\(=\frac{\left(3.4.12^{16}\right)^2}{11.2^{13}.4^{11}-16^9}\)

\(=\frac{3^2.4^2.12^{32}}{11.2^{13}.2^{22}-2^{26}}\)

\(=\frac{3^2.2^4.2^{64}.3^{32}}{11.2^{35}-2^{26}}\)

\(=\frac{3^{34}.2^{68}}{2^{26}\left(11.2^9-1\right)}\)

\(=\frac{3^{34}.2^{42}}{11.2^9-1}\)

Còn lại làm típ nha :)

tự làm đi bạn dễ mà

\(\dfrac{\left(3.4.2^{16}\right)^2}{11.2^{13}.4^{11}-16^9}\)

\(=\dfrac{\left(3.2^2.2^{16}\right)^2}{11.2^2.\left(2^2\right).11-\left(2^4\right)^9}\)

\(=\dfrac{3^2.\left(2^2\right)^2.\left(2^{16}\right)^2}{11.2^2.2^{22}-2^{36}}\)

\(=\dfrac{3^2.2^4.2^{32}}{11.2^{24}-2^{36}}\)

\(=\dfrac{3^2.2^{34}}{11.2^{24}-2^{36}}\)

\(=\dfrac{3^2.2^{24}.2^{10}}{11.2^{24}-2^{12}.2^{24}}\)

\(=\dfrac{3^2.2^{24}.2^{10}}{\left(11-2^{12}\right).2^{24}}\)

\(=\dfrac{3^2.2^{10}}{11-2^{12}}\)

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