the square root of (-8ab^-2)
-Anonymous
√(-8ab ̄ ²)
→ √[(-8a)/b²]
→ √(-1)·√(8)·√(a)·√(1/b²)
→ 2√(2)·i·√(a)·|1/b|
→ √(a)·2√(2)·|1/b|·i
Solution: √(-8ab ̄ ²) → √[(-8a)/b²] or √(a)·2√(2)·|1/b|·i
*Note that you can rewrite the radical and keep it as shown in the first step; however, if you'd like to seperate the radicals so they are apart, follow the remaining steps. If you have any more questions or require further assistance, feel free to ask; I'd be glad to assist you.
