Questions & Step-by-Step Solutions
Which of the following is true for the expression 4^(x) = 16?
Correct Answer: x = 2
Steps
Concepts
Step 1: Start with the equation 4^(x) = 16.
Step 2: Recognize that 16 can be rewritten as a power of 4.
Step 3: Rewrite 16 as 4^(2) because 4 times 4 equals 16.
Step 4: Now the equation looks like 4^(x) = 4^(2).
Step 5: Since the bases are the same (both are 4), we can set the exponents equal to each other.
Step 6: This gives us the equation x = 2.
