As we have already learnt the concept of exponent which is a shorthand notation. Let us learn about zero exponent which means for any non zero integer a^{0} is 1.
Let us try to solve few examples :

3^{1}

2^{5}
In the first example 3^{1}. Here 3 is multiplied itself for 1 time we get as 3.
Therefore for 3^{1} we get the result as 3
Coming to second example 2^{5}. Here 2 is multiplied itself for 5 times,
i.e., 2 x 2 x 2 x 2 x 2 we get as 32.
Therefore for 2^{5} we get the result as 32.
Let us try to solve few more examples by the two patterns below :
Exponents 
Values 
Exponents 
Values 
2^{4} 
= 16 
3^{4} 
= 81 
2^{3} 
= 8 
3^{3} 
= 27 
2^{2} 
= 4 
3^{2} 
= 9 
2^{1} 
= 2 
3^{1} 
= 3 
2^{0} 
= ? 
3^{0} 
= ? 
In the above table the exponents, i.e., 2^{4},2^{3},2^{2},2^{1},2^{0} are decreasing by power 1, whereas the values, i.e., 16,8,4,2 are decreasing by half.
Let us follow it and solve the value of 2^{0}, here half of 2 is 1.
Therefore we get the result for 2^{0} as 1.
Coming to other exponents, i.e., 3^{4},3^{3},3^{2},3^{1},3^{0} are decreasing by power 1, whereas the values, i.e., 81,27,9,3 are decreasing by onethird.
Let us try to follow it and solve the value of 3^{0}, here half of 3 is 1.
Therefore we get the result for 3^{0} as 1.
Similarly we can say
4^{0}=1, 5^{0}=1, 6^{0}=1 and so on….
Thus for any non zero integer a, we get a^{0} = 1.
The examples have been illustrated in the video below :
