Example

3(r+2s)=2t-4
a⋅(b-2)=3b
3(r+2s)=2t-4
a⋅(b-2)=3b

Question

$$99m-4m\ 56cm=......$$

Answer

$$99*m-224*m^2*c$$

Solution


Take out the constants.
\[99m-(4\times 56)mmc\]
Simplify  \(4\times 56\)  to  \(224\).
\[99m-224mmc\]
Use Product Rule: \({x}^{a}{x}^{b}={x}^{a+b}\).
\[99m-224{m}^{2}c\]
