Given that 27 1 x 9 find x - WAEC Mathematics 2000 Question
Given that \(27^{(1+x)}=9,)\ find x
A
-3
B
\(\frac{-1}{3}\)
C
\(\frac{5}{3}\)
D
2
correct option: b
\(27^{(1+x)}=9\
3^{3(1+x)}=3^2\
3(1+x)=2\
3+3x = 2\
3x = -1
x = \frac{-1}{3}\)
3^{3(1+x)}=3^2\
3(1+x)=2\
3+3x = 2\
3x = -1
x = \frac{-1}{3}\)
