2m = 8
= 8 ÷ 2 = 4
4 {tex}\times{/tex} 4 = 16
m² - 1
16 - 1 = 15
m² + 1
16 + 1 = 17
so the Pythagorean triplets are 8,15,17

2Thank You

Sia ? 6 years, 6 months ago

Earnings Per Month = RS. 32000
Money spent on food = {tex}\frac{1}{4}\times32000{/tex} = 8000
Money spent on house rent = {tex}\frac{3}{10}\times(32000 - 8000){/tex} = 7200
Money spent on children education = {tex}\frac{5}{10}{/tex}{tex}\times{/tex}(32000 - (8000 + 7200)) = 8,400
Money Left = 32000 - (8000 + 7200 + 8,400) = 8,400
