Answer:

An expression =
3^(9)

The area of San Bernardino County is 19,683 square miles.

Explanation:

The are of San Bernardino County is about 3 to the 9 power square miles.

Here 3 to the 9 power means " base 3 and the exponent is 9"

=
3^(9)

This means we have to multiply 3 itself by 9 times.


3^(9) = 3.3.3.3.3.3.3.3.3

= 9.9.9.9.3

= 81.81.3

= 6561.3

= 19,683 square miles

The area of San Bernardino County is 19,683 square miles.
