Correct Answer
A. \(2^4\times45\times49\)
Step 1
Concept
In an incomplete form, composite factors remain.
Step 2
Why this answer is correct
Both 45 and 49 are composite.
Step 3
Exam Tip
\(2^4\times45\times49\) must be changed into \(2^4\times3^2\times5\times7^2\). चरण 1: अधूरे रूप में संयुक्त गुणनखंड बचा रहता है। चरण 2: 45 और 49 दोनों संयुक्त हैं। चरण 3: \(2^4\times45\times49\) को \(2^4\times3^2\times5\times7^2\) में बदलना होगा।
