Answer 2

An exponent on index is a number written to the right and the little above the base. It indicates the number of times the base occurs in the product.

For e.g

X² it is read as X squared or X raised to the power 2 or X to the power 2.

Here X is the base & 2 is the exponent or index.

· If p/q is a rational number and m is a positive integer then (p/q)^m = p^m/q^m

· If x be any rational number and m, n be any integers then x^m × x^n= x^m+n

· If x be any non zero rational number and m,n be any positive integers such that m>n ,then x^m ÷ x^n= x^m-n

· If x be any non zero rational number and m,n be any positive integers such that m<n ,then x^m ÷ x^n= 1/ x^n-m

· If x be any non zero rational number then x^0= 1

· If x be any non zero rational number then x-¹= 1/x

· If x be any non zero rational number & m be any positive Integer then x^-m=1/x^m

· If x be any non zero rational number & m,n be any positive Integer then( x^m)^n= x^mn.

· If x be any non zero rational number & m be any positive Integer then x^m × y^ m=(XY)^m
