Unless the integer is fractional it is not an irrational number.
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)]
A whole number with a fractional part attached is called a mixed number. Hope this helps!
An integer is a whole number (positive, negative, or zero), and does not include a fractional or decimal part. Integers are 0, 1, -1, 2, -2, 3, -3, etc.
Yes, that is the basic idea - if the exponent (the number with a superscript) is a positive integer. However, negative and fractional exponents are also defined; you can verify this with any scientific calculator (use a positive number as the base, in this case).Note: In a number such as 103, 10 is the base, 3 is the exponent.Yes, that is the basic idea - if the exponent (the number with a superscript) is a positive integer.
