Transcript text: (a) $-81^{\frac{1}{4}}=$ (b) $(-1024)^{\frac{1}{5}}=$

Solution

Solution Steps

Step 1: Calculate $ -81^{\frac{1}{4}} $

To find $ -81^{\frac{1}{4}} $, we compute the fourth root of -81. The result is a complex number given by: \[ -81^{\frac{1}{4}} = 2.1213 + 2.1213j \]

Step 2: Calculate $ (-1024)^{\frac{1}{5}} $

Next, we calculate $ (-1024)^{\frac{1}{5}} $, which is the fifth root of -1024. The result is also a complex number: \[ (-1024)^{\frac{1}{5}} = 3.2361 + 2.3511j \]

Final Answer

The results for the calculations are: \[ -81^{\frac{1}{4}} = \boxed{2.1213 + 2.1213j} \] \[ (-1024)^{\frac{1}{5}} = \boxed{3.2361 + 2.3511j} \]
