Q
Q: If log_2(x) + log_2(4) = 5, find x.
Solution:
log_2(x) + 2 = 5 => log_2(x) = 3 => x = 2^3 = 8.
Steps: 8
Show Steps
Step 1: Start with the equation log_2(x) + log_2(4) = 5.
Step 2: Recognize that log_2(4) is equal to 2 because 2^2 = 4.
Step 3: Substitute 2 for log_2(4) in the equation: log_2(x) + 2 = 5.
Step 4: To isolate log_2(x), subtract 2 from both sides: log_2(x) = 5 - 2.
Step 5: Simplify the right side: log_2(x) = 3.
Step 6: Convert the logarithmic equation to exponential form: x = 2^3.
Step 7: Calculate 2^3, which equals 8.
Step 8: Therefore, the value of x is 8.
