Question

determinati nr natural care verifica relatiile:x^2:2^2=3^2 25^2-x^2=24^2 x:10^3=10^0 441:x=21^2 x-2^5=5^3 324:x=(3^2*2)^2

Answer 1

x^2:2^2=3^2
x^2=3^2 x2^2
x^2=6^2
x=6

25^2-x^2=24^2
25^2-24^2=x^2
(25-24)(25+24)=x^2
1*49=x^2
x^2=49=7^2
x=7

 x:10^3=10^0
 x:10^3=1
x=1*10^3
x=1000

441:x=21^2
21^2:x=21^2
x=1

 x-2^5=5^3
 x=5^3 +2^5
x=125+32=157

324:x=(3^2*2)^2
18^2:x=18^2
x=1
