Question

(1/7)^2 . 1/7 . 1/49²

Answer 1

\(\left(\dfrac{1}{7}\right)^2.\dfrac{1}{7}.\dfrac{1}{49^2}\)

= \(\dfrac{1}{49}.\dfrac{1}{7}.\dfrac{1}{2401}\)

= \(\dfrac{1}{823543}\)

Answer 2

\(\left(\dfrac{1}{7}\right)^2\cdot\dfrac{1}{7}\cdot\left(\dfrac{1}{49}\right)^2=\left(\dfrac{1}{7}\right)^5\)

Answer 3

\(\left(\dfrac{1}{7}\right)^2.\dfrac{1}{7}.\dfrac{1}{49^2}\) 

\(=\dfrac{1}{7^2}.\dfrac{1}{7}.\dfrac{1}{\left(7^2\right)^2}\) 

\(=\dfrac{1}{7^3}.\dfrac{1}{7^4}\) 

\(=\dfrac{1}{7^7}\)  \(\left(=\dfrac{1}{823543}\right)\)
