Answer 1

$\huge\bold{Question:-}$

• If A$\sub$B
• Find AUB

$\huge\bold{Solution:-}$

If A$\sub$B then AUB = B

Let us take one example:-

Let A ={1,2,3,4}

B ={1,2,3,4,5,6}

Here,

A is $\sub$ B

AUB = {1,2,3,4} U {1,2,3,4,5,6}

AUB = {1,2,3,4,5,6}

$\huge\bold{Final Answer:-}$

If A$\sub$ B then AUB = B
