Step 1: Write both numbers in scientific notation. For more information, use the SN Converter.
$$ 2040 = 2.04\cdot 10^{3} $$$$ 1 = 1 $$Step 2: Multiply the numeric parts. Note that in intermediate calculations, we need 6 significant digits.
$$ 2.04 \cdot 1 \approx 2.04 $$Step 3: Multiply $10^{ 3 }$ by $10^{ 0 }$:
$$ 10^{ 3 } \cdot 10^{ 0 } = 10^{ 3+0 } = 10^{ 3 } $$Step 4: Write the solution as the product of the numbers obtained in steps two and three.
$$ 2.04 \cdot 10^{ 3 } $$
