Explanation

To simplify the expression (√64a³)-1, we can break it down into two steps.Step 1: Simplify the square root of 64a³.The square root of 64 is 8, and the square root of a³ is a^(3/2). Therefore, we can rewrite the expression as 8a^(3/2).Step 2: Subtract 1 from the simplified expression.8a^(3/2) - 1Therefore, the simplified expression is 8a^(3/2) - 1.
