To simplify the expression \((5 \times 10^6) \times (2 \times 10^{-2})\) and put it in scientific notation, we will follow the steps you've outlined:
Step 1: Simplify the Coefficients
Multiply the coefficients:
\[ 5 \times 2 = 10 \]
Step 2: Simplify the Exponents
Add the exponents of 10:
\[ 10^6 \times 10^{-2} = 10^{6 + (-2)} = 10^{6 - 2} = 10^4 \]
Step 3: Combine the Results
Combine the results from Steps 1 and 2:
\[ 10 \times 10^4 \]
This can be expressed as:
\[ 10^1 \times 10^4 \]
Step 4: Change to Scientific Notation
Now add the exponents:
\[ 10^{1 + 4} = 10^5 \]
In scientific notation, \(10\) is actually \(1.0 \times 10^1\), therefore:
\[ 1.0 \times 10^1 \times 10^4 = 1.0 \times 10^{5} \]
Final Answer
Thus, the final answer in scientific notation is:
\[ \boxed{1.0 \times 10^5} \]
