Solution Steps

To multiply powers of the same base, add their exponents. Add 11 and -31 to get -20.

$$\frac{9\times 10^{9}\times \left(16\times 10^{-19}\right)^{2}}{667\times 10^{-20}\times 91\times 166\times 10^{-27}}$$

To multiply powers of the same base, add their exponents. Add -20 and -27 to get -47.

$$\frac{9\times 10^{9}\times \left(16\times 10^{-19}\right)^{2}}{667\times 10^{-47}\times 91\times 166}$$

To divide powers of the same base, subtract the denominator's exponent from the numerator's exponent.

$$\frac{9\times 10^{56}\times \left(16\times 10^{-19}\right)^{2}}{91\times 166\times 667}$$

Calculate 10 to the power of 56 and get 100000000000000000000000000000000000000000000000000000000.
