Answer
Expanded form of 56,439
$\begin{array}{l}=5 \times 10000+6 \times 1000+4 \times 100+3 \times 10+9 \times 1 \\ =5 \times 10^4+6 \times 10^3+4 \times 10^2+3 \times 10^1+9 \times 10^0\end{array}$
which is the required exponential form in powers of 10.
$\begin{array}{l}=5 \times 10000+6 \times 1000+4 \times 100+3 \times 10+9 \times 1 \\ =5 \times 10^4+6 \times 10^3+4 \times 10^2+3 \times 10^1+9 \times 10^0\end{array}$
which is the required exponential form in powers of 10.
