What is Index Notation in maths?

Question

thanks for the help!

Answer 1

Index notation is writing 2x2x2 as 2³ etc. The superscript, 3, is called an index.

So 200=2³x5² is the prime factorisation of 200 written in index form.

Answer 2

Index notation is used in mathematics to refer to the elements of matrices or the components of a vector. The formalism of how indices are used varies according to the discipline. In particular, there are different methods for referring to the elements of a list, a vector, or a matrix, depending on whether one is writing a formal mathematical paper for publication, or when one is writing a computer program.

Answer 3

Operations on Cartesian components of vectors and tensors may be expressed very efficiently and clearly using index notation.

Answer 4

Its the little numbers that indicate how many times a number is being multiplied by itself.
