14. \( \left(6 \times 10^{7}\right)\left(4 \times 10^{7}\right) \)

To multiply these two numbers, you first multiply the coefficients and then add the exponents of 10. So, \(6 \times 4 = 24\) and \(10^{7} \times 10^{7} = 10^{14}\). Therefore, the final result is \(24 \times 10^{14}\). If you want this in standard scientific notation, you can write it as \(2.4 \times 10^{15}\). Don't forget, scientific notation makes it easy to handle large numbers, but it's essential to keep the coefficients between 1 and 10! If you end up with a coefficient that’s 10 or more, simply adjust it, changing the exponent accordingly. It’s like keeping your numerical friends in line!
