Which choices are real numbers. Check all that apply. A. (-1024)^1/4. B. (-131072)^1/16. C. (-256)^1/9. D. (-531441)^1/13

Answer 1

Answer:

B and C

Step-by-step explanation:

Because it is raised to the ^Power of 13. This choice makes the most sense.

Answer 2

The real numbers are $(-256)^{1/9}$ and $(-531441)^{1/13}$. Then the correct options are C and D.

What is a real number?

All the numbers are real number.

If the number is having iota (i), then the number becomes complex number.

A. $(-1024)^{1/4} = 4 * (-2^2)^{1/4} = 4\sqrt2 \iota$

B. $(-131072)^{1/16} = 2*(-2)^{1/16} = 2 \sqrt[16]{2} \iota$

C. $(-256)^{1/9} = -1.85$

D. $(-531441)^{1/13} = -2.76$

Then the real numbers are $(-256)^{1/9}$ and $(-531441)^{1/13}$.

Then the correct options are C and D.
