Answer 1

\(\frac{1}{7}\times\frac{1}{49}\times49^2=\frac{1}{7}\times\frac{49^2}{49}=\frac{1}{7}\times49=\frac{49}{7}=\frac{7\times7}{7}=7\)

Answer 2

\(\frac{1}{7}\cdot\frac{1}{49}\cdot49^2=\frac{1}{7}\cdot\left(\frac{1}{49}\cdot49^2\right)=\frac{1}{7}\cdot\frac{49^2}{49}=\frac{1}{7}\cdot49=\frac{49}{7}=7\)
