Step 1: Write both numbers in scientific notation. For more information, use the SN Converter.
$$ 30 = 3\cdot 10^{1} $$$$ 30 = 3\cdot 10^{1} $$Step 2: Multiply the numeric parts.
$$ 3 \cdot 3 \approx 9 $$Step 3: Multiply $10^{ 1 }$ by $10^{ 1 }$:
$$ 10^{ 1 } \cdot 10^{ 1 } = 10^{ 1+1 } = 10^{ 2 } $$Step 4: Write the solution as the product of the numbers obtained in steps two and three.
$$ 9 \cdot 10^{ 2 } $$
