As per my understanding you want to plot the given function in 2D plot .
It is just that you forgot to add '.' before '/' to do element wise operation.I will explain it with the example below
x=2:10;
y= 0.75./(log10(x)*2).^2
plot(x,y)

Something like this?
x = linspace(1,10); % or whatever interval you would like change accordingly
y = 0.75 ./(log10(x).^2).^2 % note .^ for element wise power on log10(x)
figure
plot(x,y)
% Or maybe you want the final power of 2 apply to the numerator and the
% denominator?
y = (0.75 ./(log10(x).^2)).^2
plot(x,y)

How about this?
x = linspace(0.01,0.99,100); % Avoid tricky inputs like 1
y = 0.75./(log10(x)*2).^2;
plot(x,y)

What do you mean by "in 2D" ? It is a simple function to be plotted y vs. x:
x = 2:0.01:5;
y = 0.75./(log10(x)*2).^2;
plot(x,y)
