Question
$4 \times 10^5+3 \times 10^4+2 \times 10^3+1 \times 10^0 = 432010$
✓

Answer

Take $LHS$
$=4 \times 10^5+3 \times 10^4+2 \times 10^3+1 \times 10^0$
$=4 \times 100000+3 \times 10000+2 \times 1000+1 \times 1\left[\therefore a^0=1\right]$
$=400000+30000+2000+1$
$=432001\neq\text{RHS}$
Hence, $\text{LHS}\neq\text{RHS}$
