Answer:

Exact solution to the equation is 10-log4(x+6) = 9 is -2

Explanation:

As we have given the logarithm equation in the question that

[tex]10-log4(x+6)=9[/tex]   ……….(1)

Now by using the logarithm property, we know that  

x+6>0

So x>-6

Now from equation 1

[tex]log4(x+6)=1[/tex]

As we know the anti log property as [tex]loga(x)=b[/tex] then it becomes [tex](x)=(a)^b[/tex]

Now by using anti log Properties, the above equation would becomes  

[tex]x+6=(4)^1[/tex]

[tex]x+6=(4)[/tex]

[tex]x=-6+(4)[/tex]

So  x=-2

Hence the possible value of x that satisfy the given logarithm equation is -2.
