$1.6785 \cdot 10^{6}$ $1.6785*10^6$

Explanation:

Way 1
$8.5 \cdot 10^{3} = 0.0085 \cdot 10^{6}$ $8.5*10^3=0.0085*10^6$
$1.67 \cdot 10^{6} + 0.0085 \cdot 10^{6} = 1.6785 \cdot 10^{6}$ $1.67*10^6+0.0085*10^6=1.6785*10^6$

Way 2
$1.67 \cdot 10^{6} = 1670 \cdot 10^{3}$ $1.67*10^6=1670*10^3$
$1670 \cdot 10^{3} + 8.5 \cdot 10^{3} = 1678.5 \cdot 10^{3} = 1.6785 \cdot 10^{6}$ $1670*10^3+8.5*10^3=1678.5*10^3=1.6785*10^6$

It is $1670000 + 8500 = 1755000$ $1670000+8500=1755000$

Explanation:

$1.67 \cdot 10^{6} = 1.67 \cdot 1000000$ $1.67*10^6=1.67*1000000$
$8.5 \cdot 10^{3} = 8.5 \cdot 1000$ $8.5*10^3=8.5*1000$
