Step 1: Write both numbers in scientific notation. For more information, use the SN Converter.
$$ 168200000 = 1.682\cdot 10^{8} $$$$ 1 = 1 $$Step 2: Multiply the numeric parts. Note that in intermediate calculations, we need 6 significant digits.
$$ 1.682 \cdot 1 \approx 1.682 $$Step 3: Multiply $10^{ 8 }$ by $10^{ 0 }$:
$$ 10^{ 8 } \cdot 10^{ 0 } = 10^{ 8+0 } = 10^{ 8 } $$Step 4: Write the solution as the product of the numbers obtained in steps two and three.
$$ 1.682 \cdot 10^{ 8 } $$
