Solution

True
Taking RHS
$= (8 \times 10^{5}) + (7 \times 10^{4}) + (6 \times 10^{3}) + (5 \times 10^{2}) + (4 \times 10^{1}) + (3 \times 10^{0})$
$= (8 \times 100000) + (7 \times 10000) + (6 \times 1000) + (5 \times 100) + (4 \times 10) + (3 \times 1) = 800000 + 70000 + 6000 + 500 + 40 + 3 = 876543$

Hence, RHS = LHS
