Question

Determine o conjunto solução da equação:
Log2 (x+3) + log2 (x-4) = 3

Answer 1

Log2=0,301029995

Log2(x+3) +log2(x-4)=3

(0,301029995x+3,301029996) + (0,301029995x-(-3,698970004)=3

0,602059991x+(-0,397940008)=3

0,602059991x=3+0,39740008

0,602059991x=2,602059991

x=2,602059991/0,602059991

x=4,584952134
