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
It is the arabic system of numbers. The Roman was the one with Xes and Vs and Is and many other types of markings. Arabs used the 1-9 system, while 0 was taken from the hindu system as it indicates an empty space, so we got the 0-9 system that is commonly used now.
There is 150% increase in the number of volunteers.
Step-by-step explanation:
