I need to solve this equation.

3E -9 N / 1.25 E -19 C

I do not know what to do with the -9 and -19.

Exponents in the denomimator get subtracted from the exponents in the numerator.

3E -9 is a computer programmer's way of writing 3*10^-9. We don't use that notation here.

3*10^-9 N / 1.25*10^-19 C = (3/1.25)*10^10 = 2.4*10^10 N/C (or Volts per meter)

N/C is a measure of electric field strength

To solve this equation, you need to perform basic arithmetic operations. However, it seems like you are confused about how to handle the negative exponents (-9 and -19).

When you have a negative exponent, it indicates that the value should be moved to the denominator or inverted. In other words, a negative exponent flips the base number to the opposite side of the fraction.

Let's break down the equation step by step:

1. Start with the equation: 3E - 9 N / 1.25E - 19 C

2. The negative exponent -9 can be resolved by moving the 3E^(-9) N to the denominator. This gives us:

1 / (3E^9 N) * 1.25E^19 C

3. Now, we have a new fraction. To simplify it, we can multiply the numerators and denominators separately. This yields:

1 * 1.25E^19 / (3E^9 * N)

4. Finally, we can combine the E terms by subtracting the exponents. In this case, we have E^(19-9) = E^10. The equation becomes:

1.25E^10 / (3N)

And there you have it! The equation has been simplified by handling the negative exponents and combining like terms.
