Answer:
The base in the given term is 'x'
Step-by-step explanation:
The given expression is :
[tex]x^{2} +3[/tex]
The base is 'x' in the above given term,
The exponent form can be shown as :
[tex](base)^{exponent}[/tex]
Here, the number or power 2 is called the exponent and the 'x' is the base. The exponent corresponds to the number of times the base is used as a factor.
