Evaluate the following. Click on "Not a real number" if applicable. (a) \( -343^{\frac{1}{3}}=-7 \) (b) \( -64^{\frac{1}{2}} \) Not a real number

The expressions can be evaluated as follows: (a) \( -343^{\frac{1}{3}}= -7 \): This statement is true! The cube root of -343 is -7, since \((-7) \times (-7) \times (-7) = -343\). So, yay for negative cubes! (b) \( -64^{\frac{1}{2}} \): You would click on "Not a real number" for this one. The square root of -64 does not produce a real number; rather, it ventures into the realm of imaginary numbers! Specifically, it equals \(8i\), where \(i\) is the imaginary unit. Hence, real number fans, beware!
