Answer 2

The product of rational number with its reciprocal is always equal to 1.

square of 24 will have 6 at its unit place

57 numbers exist  betwee n the squares of 28 and 29 .

Step-by-step explanation:

32. The product of rational number with its reciprocal is always equal to 1.

Let's take an example,

Rational number = $\frac{2}{3}$

reciprocal = $\frac{3}{2}$

product = $\frac{2}{3} \times \frac{3}{2}$ = 1

33 .Squaring the above terms gives,

(A)  38 = 38² = 38 × 38 = 1444      

(B)  24 = 24² = 24 × 24 = 576

(C)  32 = 32² = 32 × 32 = 1024

( D)  45 = 45² = 45 × 45 = 2025

hence, option (B)

square of 24 will have 6 at its unit place

34. square of 29 = (29)² = 841

square of 28 = (28)^2 = 784

natural numbers exist betwee n the squares of 28 and 29 = 841- 784 = 57

hence , 57 numbers exist  betwee n the squares of 28 and 29 .
