यदि \(A=\{0,1,2,3\}\) और \(B=\{0,1,4,9\}\), तो \(A\times B\) में \(b=a^2\) वाले युग्मों की संख्या कितनी है?

If \(A=\{0,1,2,3\}\) and \(B=\{0,1,4,9\}\), how many pairs in \(A\times B\) satisfy \(b=a^2\)?

Explanation opens after your attempt
Correct Answer

C. (4)

Step 1

Concept

For (a=0,1,2,3), (b=0,1,4,9), all of which are in (B). Hence (4) pairs are obtained.

Step 2

Why this answer is correct

The correct answer is C. (4). For (a=0,1,2,3), (b=0,1,4,9), all of which are in (B). Hence (4) pairs are obtained.

Step 3

Exam Tip

(a=0,1,2,3) पर (b=0,1,4,9) सभी (B) में हैं। इसलिए (4) युग्म मिलते हैं।
