\(\frac{2048^2.2^{11}.8^6.64^7.128^3}{1024^4.4^8.16^7.2^{30}}=\frac{2^{22}.2^{11}.2^{18}.2^{42}.2^{21}}{2^{40}.2^{16}.2^{28}.2^{30}}=\frac{2^{114}}{2^{114}}=1\)

Số sản phầm đạt chuẩn chiếm :

95 : 100 = 0,95 = 95%

          Đáp số : 95%

\(-1\frac{1}{2}.\left(-1\frac{1}{3}\right).\left(-1\frac{1}{4}\right).....\left(-1\frac{1}{19999}\right)\)

=\(-\frac{3}{2}.\left(-\frac{4}{3}\right).\left(-\frac{5}{4}\right)......\left(-\frac{20000}{19999}\right)\)

= \(\frac{20000}{2}\)

= 10000
