Question

Tính giá trị của các biểu thức

\(M=\frac{51.52....99.100}{1.3...97.99.2^{50}}\)

 

Answer 1

\(M=\frac{\left(2.4....98.100\right).\left(51.52....99.100\right)}{\left(2.4....98.100\right).\left(1.3....97.99\right).2^{50}}\)

\(M=\frac{\left(2.1\right).\left(2.3\right)....\left(2.49\right).\left(2.50\right).51.52....99.100}{1.2......99.100.2^{50}}\)

\(M=\frac{2^{50}.\left(1.2....99.100\right)}{\left(1.2....99.100\right).2^{50}}\)\(=1\)

Vậy M =1

Chúc bạn học tốt ( -_- )

Answer 2

\(M=\frac{51.52...99.100}{1.3...97.99.2^{50}}\)

\(=\frac{\left(1.2.3...50\right).51.52...99.100}{1.3...97.99.2^{50}.\left(1.2.3...50\right)}\)

\(=\frac{1.2.3...99.100}{1.3...97.99.\left(2.4.6...100\right)}\)

\(=\frac{1.2.3...99.100}{1.2.3...99.100}\)
