Answer 2

To simplify the expression (9 * 10^-2)^2 * (11 * 10^5), you can follow these steps:

1. Calculate the square of (9 * 10^-2): (9 * 10^-2)^2 = (9^2) * (10^(-2 * 2)) = 81 * 10^(-4).

2. Calculate (11 * 10^5): 11 * 10^5 = 11 * 100,000 = 1,100,000.

3. Multiply the results from step 1 and step 2 together: (81 * 10^(-4)) * (1,100,000) = 81,000 * 10^(-4).

Now, you can simplify further by expressing it in standard scientific notation:

81,000 * 10^(-4) = 8.1 * 10^(5 - 4) = 8.1 * 10^1 = 81.

So, the simplified expression is 81.
