Answer 1

Resposta:

Explicação passo a passo:

$1)$

$5^{2x-3} =5^{3}$

 $2x-3=3$

 $2x=3+3$

 $2x=6$

   $x=6/2$

    $x=3$

$2)$

$7^{x+2} =7^{2}$

$x+2=2$

$x=2-2$

$x=0$

$3)$

$2^{4x-11} =2^{5}$

 $4x-11=5$

 $4x=5+11$

 $4x=16$

   $x=16/4$

   $x=4$

$4)$

$3^{2x-7} =3^{3}$

$2x-7=3$

$2x=3+7$

$2x=10$

$x=10/2$

$x=5$

$5)$

$6^{3x-20}=6^{4}$

$3x-20=4$

$3x=4+20$

$3x=24$

  $x=24/3$

  $x=8$
