Exponential Equations.

44. EXAMPLES.

1. Solve the equation

625% =3125.

Solution. We have, from the tables,

log. 3125 = 3.49485,

log. 625 = 2.79588; and also

log. log. 3125 = log. 3.49485 = 0:54343
log. log. 625 = log. 2:79588 = 0.44652
log. x = log. 1.25

0.09691; hence

x = 1.25. 2. Solve the equation

3* = 15.

Ans. W = 2.464.

3. Solve the equation

10% = 3.

Ans. x = 0.477.
