What is 04.5 in fractional notation?
04.5 is in fractional notation - a decimal fraction. However, I assume you meant in the form of a ratio.The answer is 45/10 or 9/2
Is index the same as squared?
No. The power 2, which denotes squared, is one of an infinite number of possible values for the index. Indices (or powers) can be negative, fractional, irrational or even complex.
To convert an nth root notation to one that uses fractional exponents you change the index n to the exponent?
1/n
What does fractional index mean?
A power with a rational exponent m/n in lowest terms satisfies : whenever this makes sense.
How do you work out negative fractional indices?
A number with a negative index is simply the reciprocal of the same number with a positive index. So, x-a = 1/xa Next a number to a fractional index, (a/b) is the ath power of the bth root of the number. Equivalently, it is the bth root of the ath power of the number. That is, xa/b = b√(xa) = (b√x)a. Combining these results: x-a/b = 1/(xa/b) = 1/[b√(xa)]
