Question

What is the base of log (x+7)

Answer 1

10

Explanation:

Generally we use the base 10 to any logarithmic function , which is known as common Base

so the base of log (x+7) is 10

Answer 2

Explanation:

It depends upon the 'base" of your log. Let us say that is 10 ; we can write:

log _10( x + 7 ) = 1

using the definition of log we can write:

x + 7 =10 ^1

and:

x = 10 − 7 =3

if you have a different base use the one you got instead of 10 .
