Answer:
B. 8m ^ 18
Step-by-step explanation:
(2m ^6)^3 is the same as ;
(2 ^1 × m ^ 6) ^ 3.....multiply the powers 1 and 6 by 3
2 ^ (1×3) × m ^ (6×3).....this equals;
2 ^ 3 × m ^ 18
8m^18
hope this helps :)
Subtract 4 from each side
Divide both sides by 5
Take square root of both sides
Add 3 to both sides
-2 you just subtract the 3 by 1

Answer:
I don't understand percentages
The population of the bacteria after 7 hours is 230 bacteria.
An exponential function is given by:
y = abˣ
where y, x are variables, a is the initial value of y and b is the multiplier.
Let y represent the population of bacteria after x hours.
Given that he starts his experiment with 200 bacteria, hence
a = 200
The bacteria grow at a rate of 2% per hour, hence:
b = 100% + 2% = 1.02
The exponential equation becomes:
y = 200(1.02)ˣ
After 7 hours:
y = 200(1.02)⁷ = 230
The population of the bacteria after 7 hours is 230 bacteria.
