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 .
Answer:
10
Step-by-step 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
