Answer: We can simplify the given expression as follows:
9√64 - 2√125
Since √64 = 8, we can substitute to get:
9(8) - 2√125
Since √125 = √(25 × 5) = √25 × √5 = 5√5, we can substitute again to get:
9(8) - 2(5√5)
Simplifying further:
72 - 10√5
Therefore, the expression 9√64 3 − 2√125 simplifies to 72 - 10√5.
