What values of a and b make the equation true?√(648) = √(2a × 3b)
a = 3, b = 2
a = 2, b = 3
a = 3, b = 4
a = 4, b = 3
Solution:
As we know that √648 is not a perfect square.
Therefore, we will use the prime factorization method to find the values of a and b.
Since 648 is a composite number, it has prime factors.
Thus,
648 can be expressed as the product of its prime factors.
648 = 2 × 2 × 2 × 3 × 3 × 3 × 3
The Exponential Notation of 648 = 23 × 34
Hence,
√648 = √(23 × 34)
Therefore, 3rd option is Correct.
What values of a and b make the equation true?
√(648) =√(2ᵃ × 3ᵇ)
Summary:
The values of a and b for the equation √(648) = √(2a × 3b) is a = 3 and b = 4.
