Question

1. write the base number for each expression.
2. 1.2²
3. (1/3)⁴

Explanation:

Step1: Recall base - number definition

In an exponential expression $a^n$, $a$ is the base number.

Step2: Find base for $1.2^2$

The base number is $1.2$.

Step3: Find base for $(\frac{1}{3})^4$

The base number is $\frac{1}{3}$.

Answer:

1. For $1.2^2$, the base number is $1.2$.
2. For $(\frac{1}{3})^4$, the base number is $\frac{1}{3}$.
