$18/100$

You know that

$0.01 = 1/100" "$ and $" "0.0064 = 64/10000$

This means that you can write

$sqrt(0.01) = sqrt(1/100)= sqrt(1)/sqrt(100) = 1/10$

and

$sqrt(0.0064) = sqrt(64/10000) = sqrt(64)/sqrt(10000) = 8/100$

The original expression is thus equal to

$sqrt(0.01) + sqrt(0.0064) = 1/10 + 8/100 = (10 + 8)/100 = color(green)(18/100)$
