Final answer:
To condense the expression 6 * 6 * 6 * a^b using an exponent, rewrite it as (6^3) * a^b. Then, compute the expression by evaluating 6^3, which is equal to 216. The final expression is 216 * a^b.
Step-by-step explanation:
To condense the expression 6 * 6 * 6 * a^b using an exponent, we can rewrite it as (6^3) * a^b. This means we multiply 6 by itself three times, and then multiply the result by a^b. So, the condensed form is 6^3 * a^b.
Now, to compute this expression, we can evaluate 6^3, which is equal to 6 * 6 * 6 = 216. Therefore, the final expression is 216 * a^b.
