□ 8
□ 9
rewatch

Explanation:

Step1: Understand the problem

We need to find a number \( x \) such that \( x \times x = 64 \), which is equivalent to \( x^{2}=64 \).

Step2: Test each option

• For \( x = 7 \): Calculate \( 7\times7 = 49

eq64 \).

• For \( x = 8 \): Calculate \( 8\times8=64 \), which satisfies the equation.
• For \( x = 9 \): Calculate \( 9\times9 = 81

eq64 \).

Answer:

B. 8 (assuming the options are labeled as A. 7, B. 8, C. 9)
