ПОМОГИТЕ СТЕПЕНИ
[tex]3^{3+4x} = 1,5* 2^{3+4x} [/tex]

Utem $3^{3+4x}=1,5\cdot2^{3+4x}\\\\
3+4x=t\\\\
3^t=1,5\cdot2^t\\\\
 \frac{3^t}{2^t}=1,5\\\\
 (\frac{3}{2})^t= (\frac{3}{2})^1\\\\
t=1\\\\
3+4x=1\\\\
4x=-2\\\\
x=- \frac{2}{4}\\\\
x=- \frac{1}{2}$

Ответ: $x=- \frac{1}{2}$

3³⁺⁴ˣ=1,5*2³⁺⁴ˣ
3³*3⁴ˣ=1,5*2³*2⁴ˣ
3⁴ˣ/2⁴ˣ=3*4/27
(3/2)⁴ˣ=4/9=2²/3²=(2/3)²=(3/2)⁻²
4x=-2
x=-2/4=-1/2
