let numbers are,

2x ,3x  and 5x

=====================

according to the question,

(2x)² + (3x)² + (5x)² = 950

4x² + 9x² + 25x² = 950

38x² = 950

x² = 25 

x = 5



====================

Now,

Required numbers are,

2x = 2(5) = 10 

3x = 3(5) = 15 

5x = 5(5) = 25 



i hope this will help you

Heya ✋

Let see your answer !!!!

Let the positive numbers be 2x , 3x and 5x. Then,

according to question ,

(2x) ^{2}  + (3x) ^{2}  + (5x) ^{2}  = 950 \\  =  > 4x ^{2}  + 9x ^{2}  + 25x ^{2}  = 950 \\  =  > 38x^{2}  = 950 \\  =  > x ^{2}  = 950 \div 38 \\  =  > x ^{2}  = 25 \\  =  > x =  \sqrt{25}  \\  =  > x = 5
Hence ,

1st positive number = 2 × 5 = 10

2nd positive number = 3 × 5 = 15

3rd positive number = 5 × 5 = 25






Thanks :))))
