use the exponent function on your calculator (ee or exp) to compute the following.

1.0 x 10^-14
-----------------
4.2 x 10^8

1 answer

To calculate the expression \( \frac{1.0 \times 10^{-14}}{4.2 \times 10^{8}} \) using the exponent function, you can follow these steps:

  1. Convert both numbers into their decimal forms:

    • \( 1.0 \times 10^{-14} = 0.00000000000001 \)
    • \( 4.2 \times 10^{8} = 420000000 \)
  2. Now, plug these values into the division: \[ \frac{0.00000000000001}{420000000} \]

  3. Perform the division:

    • This can be simplified as moving the decimal place to make it easier: \[ \frac{1.0}{4.2} \times \frac{10^{-14}}{10^{8}} = \frac{1.0}{4.2} \times 10^{-14 - 8} = \frac{1.0}{4.2} \times 10^{-22} \]
  4. Calculate \( \frac{1.0}{4.2} \): \[ \frac{1.0}{4.2} \approx 0.2381 \quad (approximately) \]

  5. Now, combine the results: \[ 0.2381 \times 10^{-22} = 2.381 \times 10^{-23} \]

Thus, the result of the calculation is approximately: \[ 2.381 \times 10^{-23} \]
