Introduction to negative exponents algebra:

In mathematics negative exponents algebra is very simple topic. In algebra exponents are called as powers. Algebra exponents are very important part of mathematics. Exponents are denoted that a number is multiplied by same number for a given several times. The exponent of a number is says how many times to use the copy of the number in a multiplication. Negative exponent is dividing the inverse of multiplying.

Example:

2-3 = '1/2^3' ='1/8'

'(1/6)^-1' = 6.

Laws of Negative Exponents Algebra:

a-n ='1/a^n'

a-n is reciprocal of an

'1/a^-n' =an

'1/a^-n' is same as an

Rules for exponents:

x1

=

x

x0

=

1

xmxn

=

xm+n

'x^m/x^n'

=

xm-n

(xm)n

=

xmn

(xy)n

=

xnyn

(xy)n

=

xn yn

Suppose x would be zero, x= 0 what we do?

Positive Exponent algebra means (n>0) 0n = 0

Negative Exponents algebra means (n
