\(x:\left(-\frac{4}{3}\right)^{15}=\left(-\frac{4}{3}\right)^{17}\)
=> \(x=\left(-\frac{4}{3}\right)^{17}.\left(-\frac{4}{3}\right)^{15}\)
=> \(x=\left(-\frac{4}{3}\right)^{32}=\frac{4}{3}^{32}\)( vì có số mũ là chẵn )
Vậy \(x\in\left\{\frac{4}{3}^{32}\right\}\)
X : ( -4/3)^15 = (-4/3)^17
X = (-4/3)^17. ( -4/3) ^ 15
X = ( -4/3) ^ 32
Vậy X= (-4/3)^32
chúc bạn làm bài tốt
\(x:\left(-\frac{4}{3}\right)^{15}=\left(-\frac{4}{3}\right)^{17}\)
=> x = \(\left(-\frac{4}{3}\right)^{17}.\left(-\frac{4}{3}\right)^{15}\)
=> x = \(\left(-\frac{4}{3}\right)^{17+15}\)
=> x = \(\left(-\frac{4}{3}\right)^{32}\)
Vậy x = \(\left(-\frac{4}{3}\right)^{32}\).
Chúc bạn học tốt!
