Step 1: Write both numbers in scientific notation. For more information, use the SN Converter.
$$ 2.24\cdot 10^{19} = 2.24\cdot 10^{19} $$$$ 4\cdot 10^{12} = 4\cdot 10^{12} $$Step 2: Divide the numeric parts. Note that in intermediate calculations, we need 6 significant digits.
$$ \frac{ 2.24 }{ 4 } \approx 0.56 $$Step 3: Divide $10^{ 19 }$ by $10^{ 12 }$:
$$ \frac{ 10^{ 19 } }{ 10^{ 12 } } = 10^{ 19 - 12 } = 10^{ 7 } $$Step 4: Write the solution as the product of the numbers obtained in steps two and three.
$$ 0.56 \cdot 10^{ 7 } $$Step 5: Number 0.56 smaller than 10.
To fix this, we need to move the decimal point one place to the right and subtract 1 from the exponent.
