Answer:

Step-by-step explanation:

Answer 2

Sol.1

⅙ and ⅕

Multiplying both the numbers with with each other's denominator.

i.e. ⅙×5 and ⅕×6

This gives us

5/30 and 6/30

Now, we will multiply these obtained number with 5.

5/30×5 and 6/30×5

25/150 and 30/150

Thus, three rational number between 25/150 and 30/150 are 26/150, 27/150 and 28/150.

Sol.2

i) 1/2+√3 = 1/2+√3 × 2-√3/2-√3= 2-√3

ii) 5/√3-√5=5/√3-√5×√3+√5/√3+√5

=5(√3+√5)/3-5

=(-5/2)(√3+√5)

Sol.3

g(x)=5+2x

x=-5/2

p(x)=x³+3x²+3x+1

p(-5/2)=(-5/2)³+3(-5/2)²+3(-5/2)+1

= -125/8+75/4-15/2+1

=-125/8+75/4-15/2+1/1

= -125+150-60+8/8

= -125+150-60+8

=-27/8
