bcoz 0 is rational

Answer 2

Step-by-step explanation:

Given  Which one of the following is a rational number:

a. √3 b. √2 c. 0 d. √5

2. 0.6666 in p/q form is

3. 4 1/8 in decimal form is:

(a) 4.125 6) 415 (6) 4.15 (a) 0.415

4. The value of (3+√13)(3-√13) is:

(a)0 (b)6 (c)9 (d)3

5. The value of ( √5 + √2)^is:

(a) 7+2√5 (b) 1+5√2 (c) 7+2√10 (d) 7-2√10

6. The value of (√5+ √2)(√5 - √2)is:

(a) 10 (b) 7 (¢)3

• (d) √3
• 1. Option C. 0 is a rational number
• 2. 6666 / 10000  or 3333 / 5000 is p/q form
• 3. 4 1/8 will be 33 / 8 in fractional form, on dividing we get 4.125
• 4. The value of (3 + √3) (3 - √3)  
• This is in the form of (a + b)(a – b) = a^2 – b^2
•                                                        = 3^2 – (√3)^2
•                   = 9 – 3  
•           = 6
• 5. The value of (√5 + √2) (√5 - √2) is  
•                               This is in the form of (a + b)(a – b) = a^2 – b^2
•                                                        = √5^2 – (√2)^2
•                   = 5 – 2  
•                                             = 3
