Question

What is the greatest common factor of x⁴ and x⁵?
a. x⁴
b. x³
c. x²
d. x

Answer 1

The greatest common factor (GCF) of x⁴ and x⁵ is x⁴.

Step-by-step explanation:

The greatest common factor (GCF) of x⁴ and x⁵ can be found by identifying the highest power of x that divides both terms. Since x⁴ is a factor of x⁵ (x⁵ = x⁴ * x), the GCF is x⁴.

Therefore, the correct answer is a. x⁴.
