Answer:
After 46 years, the population of this country will be doubled.
Step-by-step explanation:
Given that,
The population of a certain country is growing rate 1.5%.
The formula for this is

t= time in years
k=population growth rate.
Here k=1.5%
= 0.015

≈46 years
After 46 years, the population of this country will be doubled.
This question is essentially just determining whether you understand the definition of integers and square roots. The square root of a quantity is a number that when multiplied with itself gives that quantity. The square root of 68 is expressed as:
√68 = 8.25
The square root of 68 is roughly 8.25. Now, an integer is simply a whole number, which is a number that is not a fraction. Therefore, the smallest integer that is greater than 8.25 is simply the next whole number, which is 9.
The smallest integer greater than the square root of 68 is 9.
6^2 is the correct answer
