Question

Help!!!! f(x)=27^(2x+3)=9^3

Answer 1

here x is equal to -1 because
$6x + 9 = - 3$

Answer 2

Hi there !

_______________________

$27 {}^{(2x + 3)} = 9 {}^{3 } \\ \\ 3 {}^{3(2x + 3)} = 3 {}^{2} {}^{(3 )} \\ \\ \cancel3 \: {}^{6x + 9} = \cancel3 \: {}^{6} \\ \\ 6x + 9 = 6 \\ \\ 6x = 6 - 9 \\ \\ 6x = - 3 \\ \\ x = \frac{ - 3}{6} \\ \\ x = \frac{ - 1}{2}$
