Answer 1

1. 2

sec c

12. 6+√2

let us assume 6+√2is rational

a rational number can be written in p/q form (q not = to 0)

so,

6+√3= a/b(a,bnot= 0)

√3=a/b-6

√3=a-6b/b

v already know that √3 is irrational so

Our assumption is wrong hence 6+√3 is irrational

6.from 5 to 33(3*5=15 to 3*33=99)

9.hcf=3

lcm= 2

15.according to the formula by subs the values and is 135
