x (3-5) + (4b)
= x ( -2) + (4b), since x=8 b=3
= -16 + 12
= -4
What I did there is substitution
Replacing x with 8 ,and b with 3
So -16 is the product of (-2) and 8
And 12 is the product of 4 and 3
FYI: -2 is the result of 3 - 5
Log (base8) 2 = 1/3
Log (base 8) (4x^2) + Log (base 8) 4 + 2Log (base 8) x = 2/3 + 2 Log (base 8) x
1/3 + 2/3 + 2 Log (base 8) x = 1
2 Log (base 8) x = 0
Log (base 8) x = 0
x = 8^0
x = 1.
Answer:
The value of f[ g(x) ] = 7x + 27
Step-by-step explanation:
It is given that, f( x ) = 7x + 13 and g( x ) = x + 2
<u>To find the value of f(g(x))</u>
g(x) = x + 2 and 7x + 13 (given)
Let g(x) = x + 2
f [ g(x) ] = 7(x + 2) + 13 [ substitute the value of g(x) in f(x) ]
= 7x + 14 + 13
= 7x + 27
Therefore the value of f[ g(x) ] = 7x + 27
