Answer:
10^n, where n is an odd number between 1 and 10.
Expanded form: 10 × 10 × 10 ... (n times). Standard form: 10^n.
Explanation:
An exponential expression has a base and an exponent. In this case, the base is 10 and the exponent is an odd number between 1 and 10. The expression can be written as 10^n, where n is the odd exponent between 1 and 10.
To write the expression in expanded form, we simply multiply the base 10 by itself n times, where n is the odd exponent. For example, if n is 3, then the expanded form would be 10 × 10 × 10.
To write the expression in standard form, we simply write it as 10 raised to the power of n, which is 10^n.
