Question

The general form of $456$ is

Answer 1

The general form of a three-digit number $\mathrm{xyz}$ can be written as $100\times \mathrm{x}+10\times \mathrm{y}+\mathrm{z}$ i.e $100x+10y+z$,

$456$can be split as:

$$\begin{gathered} 456=400+50+6 \\ 456=(4\times {10}^2)+(5\times {10}^1)+(6\times {10}^0) \\ 456=(4\times 100)+(5\times 10)+(6\times 1)\left[\because 400=4\times 100,50=5\times 10,6=6\times 1\right] \\ 456=(100\times 4)+(10\times 5)+(1\times 6) \end{gathered}$$

Hence, the general form of $456$ is $(100\times 4)+(10\times 5)+(1\times 6)$
