Let's simplify the expression \((5 \times 10^6) \times (2 \times 10^{-2})\) step by step.

Step 1:

Multiply the coefficients:

  • Coefficients: 5 and 2
  • Calculation: \(5 \times 2 = 10\)

Step 2:

Add the exponents to simplify:

  • Exponents: 6 and -2
  • Calculation: \(6 + (-2) = 4\)

So, we have: \[ 10 \times 10^{4} \]

Step 3:

Change the exponent for Scientific Notation:

  • In Scientific Notation, we want a coefficient between 1 and 10. So \(10\) can be written as \(1 \times 10^1\).
  • Therefore, we can write: \[ 10 \times 10^{4} = (1 \times 10^1) \times 10^{4} = 1 \times 10^{(1 + 4)} = 1 \times 10^{5} \]

Step 4:

The final answer in Scientific Notation is: \[ 1 \times 10^{5} \]

Thus, the answer is: 1 x 10^5.
