A certain number of people agree to subscribe as many rupees each as a there are subscribers. The whole subscription is 2582449 rupees. Find the number of subscribers.

Square root of (1/4) x (1/49) ÷ (25/121)
= ?(1/4) x (1/49) x (121/25)
= 11 / (2 x 7 x 5)
= 11/70

Number of members = ?2209
= 47

a² + a² = (8)²
? 2a² = 64
? a² = 32
? a = ?32 = 4?2
= 4 x 1.41
= 5.64 cm

176 = 2 x 2 x 2 x 2 x 11
So, in order to make it a perfect square, it must be multiplied by 11.

216 = 2 x 2 x 2 x 3 x 3 x 3
= (2 x 2) x 2 x ( 3 x 3) x 3

Clearly, in order to make it a perfect square, it must be divided by 2 x 3 i.e., 6 .

175760 = 2⁴ x 5 x 13 ³
= 2³ x 2 x 5 x 13³
To make perfect cube, it must be divided by 2 x 5 = 10

Total money donated = 4356 rupees

As total students are equal to the sum donated by each student.
Total Students =?4356
= 66

?256 / ?x = 2
? 16 = 2?x
? ?x = 8
? x = 64.

N = 25/16
? ?N = ?25/16
= 5/4
= 1¹/₄

?2401 = ?7^x
? 7^x = 2401 = 7⁴
? x = 4
