The nth root of a number is the same as the number raised to the power 1/n.

Thus sqrt(73) = 731/2

or

cuberoot(95) = 951/3

No. In the index form a number is expressed as a multiple of its prime factors whereas in the standard form it is expressed as a number between in the range [1, 10) multiplied by an integer power of 10. So, for example, 1728 in index form = 26*33 1728 in standard form = 1.728*103 The index form can only be used for integers.

"index" is the singular form - "indices" is the plural :)

0.001 is a fractional number in decimal form and there is no sensible way to convert it into a whole number.

If the number can be written as 2*3*5 it cannot be prime!

Index form is where a number is expressed as the exponents of its prime factors. At the moment, you have it as its prime factors. We have two 3s, so that can be given as 32 and we have four 4s, so that can be given as 44. Thus 3x3x4x4x4x4 in index form is 32x44

0.05 is a fractional number in decimal form and there is no way to convert it to a whole number.

The possessive form of "index" is "index's." For example, "the index's values are displayed in alphabetical order."
