Finding the Solution
To solve the equation log4(2) x log4(5) x 18, we first need to clarify and simplify the expression, as it appears to be an equation rather than a singular expression.
The expression is made up of logarithmic components. Let’s break it down:
Step 1: Understanding Logarithms
The logarithm, log4(b)
, refers to the power to which the base (4) must be raised to produce the number b
. For example, log4(2)
asks the question, “4 raised to what power gives 2?”
Step 2: Simplifying the Equation
Based on the given expression, we can identify:
- Calculate
log4(2)
: Using change of base formula, we can calculate this as1/2
because4^(1/2) = 2
. - Calculate
log4(5)
: This value is less straightforward, and numerical approximations can give uslog4(5) ≈ 1.161
.
Now, we multiply the results:
Step 3: Numerical Calculation
Let’s denote the values:
A = log4(2) ≈ 0.5
B = log4(5) ≈ 1.161
Thus, the product becomes:
A * B * 18 ≈ 0.5 * 1.161 * 18
Step 4: Final Calculation
Carrying out the multiplication:
0.5 * 1.161 = 0.5805
0.5805 * 18 ≈ 10.437
Conclusion
The potential solution culminates to be approximately 10.437.
