Ta có:\(\frac{16}{25}\)+ (x+\(\frac{1}{3}\))\(^2\)=1
(x+\(\frac{1}{3}\))\(^2\)= \(\frac{9}{25}\)
x+\(\frac{1}{3}\)= \(\frac{3}{5}\)
x=\(\frac{4}{15}\)
\(\frac{16}{25}+\left(x+\frac{1}{3}\right)^2=1\)
\(\left(x+\frac{1}{3}\right)^2=1-\frac{16}{25}\)
\(\left(x+\frac{1}{3}\right)^2=\frac{9}{25}=0,36\)
\(x+\frac{1}{3}=0,6=\frac{3}{5}\)
\(x=\frac{3}{5}-\frac{1}{6}\)
\(x=\frac{13}{30}\)
nhớ k cho mk nhá, điểm mk đang âm, cảm ơn nhiều!!!!
