choose the correct answer below.

a. \\(9 \cdot x \cdot x\\)
b. \\(9x^2 \cdot 9x^2\\)
c. \\(9 \cdot x \cdot 2\\)
d. \\(9x \cdot 9x\\)

Explanation:

Analyze the base and exponent

$$ x^2 = x \cdot x $$

Apply the coefficient

$$ 9x^2 = 9 \cdot x^2 = 9 \cdot x \cdot x $$

Answer:

• (A) \(9 \cdot x \cdot x\) (Correct answer)
• (B) \(9x^2 \cdot 9x^2\)
• (C) \(9 \cdot x \cdot 2\)
• (D) \(9x \cdot 9x\)
