\sqrt{180}  -  \sqrt{45 }  \\  =  \sqrt{2 \times 2 \times 3 \times 3 \times 5}  -  \sqrt{3 \times 3 \times 5 }  \\

Taking common

\sqrt{3 \times 3  \times 5} ( \sqrt{4}  - 1) \\  = 3 \sqrt{5} (2 - 1) \\  = 3 \sqrt{5}

luda_lava [24]
The answer is <span>8,686,308,783.</span>

To calculate this, we will use the equation for exponential function:
y=x(r+1) ^{n}
y - the future population
x - the current population
r - the rate of increasing the population
n - the number of years

It is given:
x = 6,486,915,022
r = 1.4% = 0.014
n = 2026 - 2005 = 21

Therefore:
y= x(r+1)^{n} =6,486,915,022*(0.014+1) ^{21} = 8,686,308,783
