Step-by-step explanation:
<u>Given </u><u>expression</u><u> </u><u>:</u><u>-</u>
It will be composite if it will has more than 2 factors ( other than 1 and itself )
<u>If </u><u>n </u><u>=</u><u> </u><u>1</u><u> </u><u>:</u><u>-</u>
<u>If </u><u>n </u><u>=</u><u> </u><u>2</u><u> </u><u>:</u><u>-</u><u> </u>
- 4*2 + 3
- 8 + 3
- 11 ( prime )
<u>If </u><u>n </u><u>=</u><u> </u><u>3 </u><u>:</u><u>-</u><u> </u>
- 4*3+3
- 12+3
- 15 ( composite )
B/3a
a/b*b/2a= ab/2ab or 1/a
1/a*b/2a=b/3a
