3. m=3
4. 2
5. hcf=xy   lcm=$x^{3} y^{2}$    
6. no as lcm is a multiple of hcf
7. no as 2 is not its prime factor
8. 4052=420*9+272  420=272*1+148   272=148*1+124   148=124*1+24  124=24*5+4   24=4*6+0 hcf=4
9. p=2 q=5
10. Suppose 15+173–√ is a rational number.  ∴15+173–√=ab, where a and b are co-prime, b≠0  ⇒173–√=ab−15  3–√=a−15b17b  a−15b17b is rational number,  3–√ is irrational.   ∴3–√≠a−15b17b  ∴ Our supposition is wrong.   ⇒15+173–√ is irrational.
11. sorry i dont know
