Medium Mathematics Chapter 1: Real Numbers Class 10 Level 11

\(2^2 \times 3^3\) को पूर्ण वर्ग बनाने के लिए कम से कम किससे गुणा करना होगा?

By the least number should \(2^2 \times 3^3\) be multiplied to make it a perfect square?

Explanation opens after your attempt
Correct Answer

B. 3

Step 1

Concept

In a perfect square, all prime exponents must be even.

Step 2

Why this answer is correct

\(2^2\) is already even, and \(3^3\) needs one more (3) to become \(3^4\).

Step 3

Exam Tip

Multiply only by the prime that has an odd exponent. चरण 1: पूर्ण वर्ग में सभी अभाज्य घातें सम होनी चाहिए। चरण 2: \(2^2\) पहले से सम है और \(3^3\) को \(3^4\) बनाने के लिए (3) चाहिए। चरण 3: केवल विषम घात वाले अभाज्य को एक बार और गुणा करें।
