Answer

$\text { Take RHS }=8 \times 10^5+7 \times 10^4+6 \times 10^3+5 \times 10^2+4 \times 10^1+3 \times 10^0$
$=8 \times 100000+7 \times 10000+6 \times 1000+5 \times 100+4 \times 10+3 \times 1$
${\left[\therefore a^0=1\right]}$
$=800000+70000+6000+500+40+3$
$=876543$
$=\text { LHS }$
Hence, $RHS = LHS.$
