Absolute Values In Radicals
Absolute Values in Radicals Absolute values in radicals is a very easy
concept, once it is mastered. Basically an absolute value is the positive square
root of the sum of the squares of the real and imaginary parts of a complex
number. An absolute value sign is two straight lines that are place around the
exponent to show that the value of the exponent is a positive number. Absolute
value signs are needed when there is an even exponent inside a radical and when
the square is taken the exponent becomes odd. Then, the odd exponent is placed
outside the radical and absolute values signs are placed around it. Absolute
value signs are needed because the exponent could be a positive or a negative
number.
X could be negative number and if it were raised to an even power, it
would become positive. But if someone would need to find the square root, the
absolute value signs would be needed to show that could be a nonnegative value.
