We can solve this. But what have you attempted for your simple home work problem?

This is one of the first tasks, but this is also the first lesson I had.

You can read about roots, solve.
I suggest you to read the function roots.

% "how to whrite this in code 0,01x^5-1.4x^3+80x+16.7"
% Commas do both statements in sequence - one after the other.
% The first statement does nothing really
0
% Now the second statement. 01 is the same as 1. Use * to multiply.
1 * x^5 - 1.4 * x ^ 3 + 80 * x + 16.7

Not sure what "solve" means to you. Do you mean plot it? Here is better code:
% Create x
x = linspace(-15, 15, 1000);
% Create y
y = x .^ 5 - 1.4 * x .^ 3 + 80 * x + 16.7;
% Plot y vs. x.
plot(x, y, 'b-', 'LIneWidth', 2);
title('y = x .^ 5 - 1.4 * x .^ 3 + 80 * x + 16.7', 'FontSize', 20);
xlabel('x', 'FontSize', 20);
ylabel('y', 'FontSize', 20);
grid on;
You didn't tag it as homework. If it is, you can't submit it or else your instructor's plagiarism detector may notice it.
