1. Find six rational numbers between

a) 3 and 4

b) 3/5 and 8/5
c) 2/3 and 5/2

2. Find: a) 641/2

b) 1251/3

3. Find a) 93/2 b) 322/5 c) 125-1/3

4. Simplify:

a) 22/3×21/5

b) 111/2÷111/4

5. Write coefficients of x2 in each of following-

a) 2+ x2+x

b) 2x-1

c) 2- x2+x3

Step-by-step explanation:

1) a) 3.1,  3.2,   3.3,  3.4, 3.5,  3.6

b)

Six rational numbers are:

2) a )

4)Simplify

5)

a) coeeficient of x² =  1

b) coeeficient of x² = 0

c) coeeficient of x² =  (-1)

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
