Exponent is referred as power of a variable. The expression $x^{m}$ is an exponential expression, where **"x"** is known as **"base"** and **"m"** is called **"exponent"**.**$x^{m}=x*x*x*....*x(m\ times)$**An equation containing exponential expression is known as exponential equation.**For example:** $x^{\frac{4}{3}}$=$256$.

There are few rules of exponents which are to be followed while solving exponential equations. These rules are known as **laws of exponents** which are as follows:**(1)** If bases are equal, then exponents will also be equal.

Let us understand laws of exponents with few examples:

$2^{3x+1}=(2^{3})^{2x}$

$2^{3x+1}=2^{6x}$ (Using law $(a^m)^n = (a)^{mn}$)

$3x+1=6x$ (Using law, if $a^m = a^n$ then m = n)

$3x=1$

$x=$$\frac{1}{3}$

$3^{2a}=26+1$

$3^{2a}=27$

$3^{2a}=3^{3}$

$2a=3$ (Using law, if $a^m = a^n$ then m = n)

$a=$$\frac{3}{2}$
