Answer 1

2)

n = 10;
for i = 1:n
fprintf("%6i %8.4f\n", i, sqrt(i));
end

--------------------------------------------------------------------

3)

a = [3,40,1,8,0];
b = [-7,5,4,16,1];
c = [];
n = 1;
while ( n<=5 )
c(n) = a(n) + b(n);
n = n + 1;
end
disp(c)

----------------------------------------------------------------------------------------------------------------------
