If logx to base 2 logx to base 4 logx to base 16= 21/4 these x is ...
Solution:
Step 1: Convert logx to base 4 into logx to base 2
Since we need to find logx to base 2, we can convert logx to base 4 into logx to base 2 using the following formula:
logx to base 4 = logx to base 2 / log4 to base 2
Substituting the values given in the question, we get:
logx to base 4 = logx to base 2 / 2
Therefore, logx to base 2 = 2*logx to base 4
Step 2: Convert logx to base 16 into logx to base 2
Using the same formula as in step 1, we can convert logx to base 16 into logx to base 2:
logx to base 16 = logx to base 2 / log16 to base 2
Substituting the values given in the question, we get:
logx to base 16 = logx to base 2 / 4
Therefore, logx to base 2 = 4*logx to base 16
Step 3: Combine the equations
Now we can substitute the two equations we derived in steps 1 and 2 into the equation given in the question:
logx to base 2 + 2*logx to base 4 + 4*logx to base 16 = 21/4
Substituting the values we derived in steps 1 and 2, we get:
logx to base 2 + 2*(logx to base 2 / 2) + 4*(logx to base 2 / 4) = 21/4
Simplifying, we get:
logx to base 2 + logx to base 2 + logx to base 2 = 21/4
3*logx to base 2 = 21/4
logx to base 2 = 7/4
Step 4: Find x
Now we can use the definition of logarithms to find x:
x = 2^(logx to base 2)
Substituting the value we found in step 3, we get:
x = 2^(7/4)
Therefore, x = 5.66 (approx)
Answer:
The value of x is 5.66 (approx).
