Evaluate.<br><br><br><br> 2<br> -2<br> 4<br> undefined
LiRa [457]

Answer:

2

Step-by-step explanation:

We have to get the value of the expression of - ∛(- 8).

Now, we can write the expression as  

- ∛(- 8)  

=-\sqrt[3]{-8}

= -(-8)^{\frac{1}{3} } {Converting into exponent form}

= -[(-2)^{3} ]^{\frac{1 }{3} } {Since (- 2) × (- 2) × (- 2) = - 8}

= - [(-2)^{3\times \frac{1}{3} } ]{Since we know that  [x^{a}] ^{b} = x^{ab}}

= - [- 2]

= 2 (Answer)
