1) \( \left(1,2 \times 10^{6}\right) \times\left(1,2 \times 10^{7}\right) \)

To multiply these two numbers in scientific notation, you simply multiply the coefficients and then add the exponents. So, \( (1.2 \times 10^{6}) \times (1.2 \times 10^{7}) = (1.2 \times 1.2) \times (10^{6} \times 10^{7}) \). Calculating that gives \( 1.44 \times 10^{(6+7)} = 1.44 \times 10^{13} \). Now you have the product \( 1.44 \times 10^{13} \), a neat way to express large numbers! It's like storing your mega-bucks in a treasure chest labeled just for easy access. If you're ever confused about multiplying in scientific notation, remember that you're really just handling two parts: the numbers in front and the powers of ten. Keep it simple, focus on one part at a time, and you'll ace it every time!
