The main reason behind this is using properties of logarithm .

when solving
There you use multiplication property and make addition to multiplication then you get extraneous solution because in plenty of cases they occur

Answer:
n2^3 bacteria, n being the initial population.
Step-by-step explanation:
compound growth equation: P=n2^t
P is total population
n is initial population
t is time
since it doubles every second hour, and there are 6 hours
6hours/2hours= doubles 3 times, thats why t=3.
The number of ways is 364 if the number of ways in which 4 squares can be chosen at random.
<h3>What are permutation and combination?</h3>
A permutation is the number of different ways a set can be organized; order matters in permutations, but not in combinations.
It is given that:
On a chessboard, four squares are randomly selected so that they are adjacent to each other and form a diagonal:
The required number of ways:
= 2(2[C(4, 4) + C(5, 4) + C(6, 4) + C(7, 4)] + C(8, 4))
= 2[2[ 1 + 5 + 15+35] + 70]
= 364
Thus, the number of ways is 364 if the number of ways in which 4 squares can be chosen at random.

Answer:2,262in.^3
Step-by-step explanation:
Given :
Runs scored by home team is (x + 7).
Runs scored by visiting team is (3x - 7).
To Find :
An expression to find how many more runs the home team scored than the visiting team. Then evaluate the expression if the value of x is 6.
Solution :
Let, number of more runs the home team scored than the visiting team is R.
R = (x + 7) - (3x - 7)
R = 14 - 2x
Now, putting value of x = 6 in above equation, we get :
R = 14 - 2( 6 )
R = 2
Hence, this is the required solution.
