If (N \_ { 3 } \cap N \_ { 4 } =) | MATH - SET THEORY | SolveeIt

If $N _ { 3 } \cap N _ { 4 } =$

$N _ { 7 }$

$N _ { 12 }$

$N _ { 3 }$

$N _ { 4 }$

Answer

$N _ { 12 }$

Explanation

$N _ { 3 } \cap N _ { 4 } = \{ 3,6,9,12,15 \ldots \ldots \} \cap \{ 4,8,12,16,20 , \ldots .$ .

= {12, 24, 36......} = $N _ { 12 }$

Trick: $N _ { 3 } \cap N _ { 4 } = N _ { 12 }$ [ $\bullet \bullet$ 3, 4 are relatively prime numbers]
