It only takes a minute to sign up. Then the problem becomes (10^-6)^99 * (10^-6)^99 We can go one step further: since we are multiplying something by itself, we can write that as a square: ((10^-6)^99)^2 This means we are raising 10 first to the -6th power, then to the 99th power, then to the 2nd power.
