Question

a, \(^{ }\)\(1,24^2\) - \(0,24^2\)

Answer 1

\(=\left(1,24-0,24\right)\left(1,24+0,24\right)=1.\left(1.48\right)=1,48\)

Answer 2

\(a,1,24^2-0,24^2\)

\(=\left(\dfrac{31}{25}\right)^2-\left(\dfrac{6}{25}\right)^2\)

\(=\dfrac{961}{625}-\dfrac{36}{625}\)

\(=\dfrac{961-36}{625}=\dfrac{37}{25}\)
