The equation is an illustration of indices and exponents
The common base used to rewrite each side of the expression is 2
The equation is given as:
[tex]2^{x + 3} -3 = 5[/tex]
Rewrite the above equation using the laws of indices and exponents as:
[tex]2^{x} * 2^{3} -3 = 5[/tex]
The above equation means that:
[tex]2^{x + 3} = 2^{x} * 2^{3}[/tex]
This means that, the common base when the expressions 2^x and 2^3 are combined is 2
Hence, the common base used to rewrite each side of the expression is 2
