It works because 7 x 9 x 10 is the same thing as 7 x 90, since 9 x 10 is just 90. So basically he is just writing more but the answer will still be the same.

Can anyone do this with steps ..
Harrizon [31]

\\ \sf\longmapsto \displaystyle{\lim_{x\to 0}}\dfrac{sinx-sin3x}{sins3x-sinx}

\boxed{\sf \displaystyle\lim_{x\to 0}\dfrac{f(x)}{g(x)}=\dfrac{\lim_{x\to 0}f(x)}{\lim_{x\to 0}g(x)}}

Now

\\ \sf\longmapsto \displaystyle{\dfrac{\lim_{x\to 0}sinx-\lim_{x\to 0}sin3x}{\lim_{x\to 0}sin3x-\lim_{x\to 0}sinx}}

\boxed{\sf \displaystyle{\lim_{x\to 0}}f(x)=f(a)}

\\ \sf\longmapsto \dfrac{sin0-sin3(0)}{sin3(0)-sin0}

\\ \sf\longmapsto \dfrac{0-0}{0-0}

\\ \sf\longmapsto \dfrac{0}{0}

\\ \sf\longmapsto 0
