Question

write the following exponential expression using radical notation. 2^1/8

Answer 1

Say you have the following expression:

. . . . .\L(−4)−32

To eliminate the "minus" from the exponent, you moved the base to the other side of the fraction line:

. . . . .\L1(−4)32

Apply the cubing:

. . . . .\L1(−64)12

In radical terms, this is:

. . . . .\L1−64√

This, of course, is not defined in the real numbers.

I have a feeling you neglected some parentheses, so the calculator interpreted the expression as:

. . . . .\L−(4)−32

This does indeed simplify to your answer:

. . . . .\L−(1432)=−(164√)=−18

Hope that helps a bit.
