Option C: is the value of a and b
Explanation:
Given that the expression
We need to determine the value of a and b
Let us consider the term and take the prime factorization of the term 648
Thus, we have,
648 divides by 2,
324 divides by 2,
162 divides by 2,
81 divides by 3,
27 divides by 3,
9 divides by 3,
Thus, we have,
Therefore, equating the powers of 2 and 3, we get,
Hence, the value of a and b is 3 and 4
Thus, Option C is the correct answer.
In the equation
divide both sides by to get
Take the base-3/2 logarithm of both sides:
Alternatively, you can divide both sides by :
Then take the base-2/3 logarith of both sides to get
(Both answers are equivalent)
