What is the value of b for b^2 = 36/64
A, B= 18/32
B,B= 9/16
C,B=6/8
D,b=72/128
A, B= 18/32
B,B= 9/16
C,B=6/8
D,b=72/128
To find the value of \( b \) for the equation \( b^2 = \frac{36}{64} \), we need to take the square root of both sides:
\( b = \sqrt{\frac{36}{64}} = \frac{\sqrt{36}}{\sqrt{64}} = \frac{6}{8} \)
Therefore, the correct answer is C. \( b = 6/8 \).
\( b = \sqrt{\frac{36}{64}} = \frac{\sqrt{36}}{\sqrt{64}} = \frac{6}{8} \)
Therefore, the correct answer is C. \( b = 6/8 \).
