Question

помогите,пожалуйста.

Answer 1

$5*5^{3-2x}=25^{4-3x} \\\\5^{1+3-2x}=5^{2(4-3x)}\\\\5^{4-2x}=5^{8-6x}\\\\4-2x=8-6x\\\\-2x+6x=8-4\\\\4x=4\\\\x=4:4\\\\x=1\\\\Otvet:1$

$36^{x}-4*6^{x}-12=0\\\\(6^{x})^{2}-4*6^{x}-12=0\\\\6^{x}=m;m>0\\\\m^{2}-4m-12=0\\\\m_{1}=6\\\\m_{2}=-2<0\\\\6^{x}=6\\\\x=1\\\\Otvet:1$
