Answer:
The base number is 12
Explanations:
Given the indices expression:
![12^4](https://img.qammunity.org/2023/formulas/chemistry/college/lxtgp8txi4uugypi5sd6itam466uh6prpt.png)
We are determining the base number. Recall from indices that if we have:
![a^b](https://img.qammunity.org/2023/formulas/mathematics/college/w62wuaqywuj6ekxvp2coh8gwpha7jmm6u0.png)
"a" serves as the base number and:
"b" serves as the exponent
Compared with the given expression you can see that:
• a = 12 (Which is the, base numbe,r)
,
• b = 4 (which is the ,exponent,)
Hence we can conclude that the base number is 12.
