Question

2) Resolva as seguintes equações: b) log 6 ( 2x + 16 ) = 2 c) log 5 ( 3x + 4 ) = 7 PRECISO URGENTEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE PRFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF

Answer 1

Resposta:

a) x = 10

b) x = 26.040,33

Explicação passo-a-passo:

b)

$log[6](2x+16)=2\\\\2x+16=6^2\\\\2x=36-16\\\\2x=20\\\\x=20/2\\\\x=10$

c)

$log[5](3x+4)=7\\\\3x+4=5^7\\\\3x=78.125-4\\\\3x=78.121\\\\x=78.121/3\\\\x=26.040,33$

Valeu!
