F=22•10^3•11•10^-2

To simplify the expression \( F = 22 \times 10^3 \times 11 \times 10^{-2} \), you can follow these steps:

1. First, multiply the coefficients: \( 22 \times 11 \)
2. Then, combine the powers of 10: \( 10^3 \times 10^{-2} \)

Calculating these:

1. \( 22 \times 11 = 242 \)
2. For the powers of ten: \[ 10^3 \times 10^{-2} = 10^{3-2} = 10^{1} \]

Now, combine the results:

\[ F = 242 \times 10^{1} = 2420 \]

So, \( F = 2420 \).
