Question

1250:(X la puterea a doua +25)=10

Answer 1

1250:(xpatrat+25)=10=>x patrat+25=1250:10=125==>x la patrat=125-25=100 deci x=10 pt ca xla patrat=100

Answer 2

am puteea rezolva asa problema :
1250/(x²+25)=10(x²+25)/(x²+25)
1250=10(x²+25)
1250=10x²+250
10x²=1250-250
10x²=1000
x²=1000/10
x²=100
x=√100
x=10
