The student of class XI of a school donated 4356 Rupees in all, for Prime Minister's National Relief Fund. Each student donated as many rupees as the number of students in the class. Find the number of students in the class.

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

Let the total number of subscribers be x.
Then, according to the question, x² = 2582449
? x = ?2582449
= 1607

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

?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

3600 = 2 x 2 x 2 x 2 x 3 x 3 x 5 x 5.

To make it a perfect cube, the given number must be divided by 2 x 3 x 3 x 5 x 5 = 450

21600 = 6 x 6 x 6 x 10 x 10
To, make the given number a perfect cube, it must be multiplied by 10.
