Divide $ 8\cdot 10^{15} $ by $ 4\cdot 10^{12} $.
Answer
$$ \dfrac{ 8\cdot 10^{15} }{ 4\cdot 10^{12} } = 2\cdot 10^{3} $$
Explanation
Step 1: Write both numbers in scientific notation. For more information, use the SN Converter.
$$ 8\cdot 10^{15} = 8\cdot 10^{15} $$$$ 4\cdot 10^{12} = 4\cdot 10^{12} $$Step 2: Divide the numeric parts.
$$ \frac{ 8 }{ 4 } = 2 $$Step 3: Divide $10^{ 15 }$ by $10^{ 12 }$:
$$ \frac{ 10^{ 15 } }{ 10^{ 12 } } = 10^{ 15 - 12 } = 10^{ 3 } $$Step 4: Write the solution as the product of the numbers obtained in steps two and three.
$$ 2 \cdot 10^{ 3 } $$This page was created using
