Question

tinh B = \(\frac{2^{15}\cdot7-2^{16}}{5\cdot2^{15}}\)

Answer 1

\(\Rightarrow B=\frac{2^{15}.7-2^{15}.2}{5.2^{15}}\)

\(\Rightarrow B=\frac{2^{15}.\left(7-2\right)}{5.2^{15}}\)

\(\Rightarrow B=\frac{2^{15}.5}{5.2^{15}}=1\)

Answer 2

Giải :

\(B=\frac{2^{15}.7-2^{16}}{5.2^{15}}=\frac{2^{15}\left(7-2\right)}{5.2^{15}}=\frac{2^{15}.5}{5.2^{15}}=1\)

Vậy B = 1

Answer 3

\(B=\frac{2^{15}.7-2^{15}.2}{5.2^{15}}=\frac{2^{15}.\left(7-2\right)}{5.2^{15}}=\frac{2^{15.5}}{5.2^{15}}=1\)

Answer 4

B=2¹⁵.7-2¹⁵.2/5.2¹⁵

B=2¹⁵.(7-2)/5.2¹⁵

B=2¹⁵.5/5.2¹⁵

B=1
