Answer:
x=1
Step-by-step explanation:
log_4(x + 3) + log_4x = 1
We know that loga(b) + loga(c) = loga(bc)
log_4(x + 3)x = 1
Raise each side to the base of 4
4^log_4(x + 3)x = 4^1
(x+3)x = 4
x^2 +3x = 4
Subtract 4 from each side
x^2 +3x -4 = 0
Factor
(x+4) (x-1) =0
Using the zero product property
x= -4 x=1
But x cannot be negative since logs cannot be negative
x=1
Answer: the nots confused me y’ is that integral or what
Step-by-step explanation:
Answer: 4³ × 5²
Step-by-step explanation:
Index Notation:
This is a short way of writing a number being multiplied by itself.
The base is the number itself and the power is the times the number is multiplied by itself.
With this we can now write the above multiplication in index notation.
we do it as follows : 4³ × 5²
Answer:
A. 4000 meters because
1 km = 1000 meters
and 4 km = 1000 × 4 = 4000
