فرض مراقبة عدد 4 — نموذج عدد 2

\[ A = (-2)^{3} + (-3)^{3} \]

\[ B = -3\times(-2)^{4} \]

\[ C = 2^{-3}\times 100\times 5^{-3} \]

\[ E = \frac{(a^{7})^{5}\times a}{a^{27}\times a^{2}} \]

\[ F = \left(\frac{7}{5}ab^{4}\right)^{6}\times\left(\frac{5}{7}a^{3}b^{2}\right)^{4} \]

\[ C = \left[\left(-\frac{5}{4}\right)^{3}\right]^{-2}\times\frac{125}{64} \]

\[ D = \frac{\left(\frac{5}{3}\right)^{-3}\times\left(\frac{1}{2}\right)}{\left(-\frac{1}{2}\right)^{2}\times\left(\frac{3}{5}\right)^{2}} \]
