Rational Exponents with Negative Coefficients - Problem 4 387 views
Recall that the square root of negative one is defined as i, so if we're doing an even root of a negative value, we'll have no real solution, BUT if it's an odd root of a negative value, we'll have a negative answer. For fractional exponents, re-write the expression in radical form. Apply the root to each part of the term, as done in the examples here, to simplify. Be very precise with negative coefficients and whether the negative is being raised to the power or just the integer itself- we explore the importance of parentheses here.
