Question

1212 : [(5⁷ : 5³ . 6) - ( 20 - 13)²]

Answer 1

\(1212\div\left[\left(5^7\div5^3.6\right)-\left(20-13\right)^2\right]\)

\(=1212\div\left[\left(5^4.6\right)-7^2\right]\)

\(=1212\div\left[3750-343\right]\)

\(=1212\div3701=\dfrac{1212}{3701}\)

Answer 2

\(=\dfrac{1212}{5^4\cdot6-7^2}=\dfrac{1212}{3701}\)
