Question:

Some calculators cannot display results of an antilog calculation if the power of 10 is greater than 99. This shortcoming can come into play for determining equilibrium constants of redox reactions, which are sometimes quite large. Solve the following expressions for K: 

(a) log K = 45.63,

(b) log K = 25.00,

(c) log K = 20.63. What is the relationship among the three expressions and the three answers? How can you use this relationship to solve problems that exceed 1099, even if your calculator will not carry out the calculation directly?
