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

(-3.2 x10^-7) (-8.6 x 10^-9)

1 answer

To compute \((-3.2 \times 10^{-7}) \times (-8.6 \times 10^{-9})\), you multiply the coefficients and add the exponents of the powers of ten.

  1. Multiply the coefficients: \[ -3.2 \times -8.6 = 27.52 \] (The negatives cancel out.)

  2. Add the exponents: \[ -7 + (-9) = -16 \]

Now combine the results: \[ 27.52 \times 10^{-16} \]

To express this in scientific notation: \[ 2.752 \times 10^{-15} \]

So, the final result is: \[ \mathbf{2.752 \times 10^{-15}} \]
