Question

¿qué expresión tiene una base con un exponente de 4?
4z³
4·x·y
p + 4
3m⁴

Explanation:

Step1: Recall exponent notation

In a term like \( a^n \), \( a \) is the base and \( n \) is the exponent. We need to find which expression has a base with exponent 4.

Step2: Analyze each option

• \( 4z^3 \): The exponent on \( z \) is 3, 4 is a coefficient, not a base with exponent.
• \( 4\cdot x\cdot y \): This is a product of 4, \( x \), and \( y \), no exponents (or exponents of 1, but not 4).
• \( p + 4 \): This is a sum, no exponents in the base - exponent form.
• \( 3m^4 \): Here, the base is \( m \) and the exponent is 4 (the 3 is a coefficient).

Answer:

\( 3m^4 \)
