Also, is x*5x equal to 6x or 5x^2?
When multiplying variables, you need to add their exponents.
To answer your specific questions:
x^{2} * 5x = 5x^{3}
x * 5x = 5x^{2}

(In addition to John's response)
Algebraically: x = x^{1} , x · x = x^{1} · x^{1} = x^{1+1} = x^{2} ...... etc.
x^2*5x = x^{2} · 5 · x = 5 · x^{2} · x^{1} = 5 · x^{2+1} = 5x^{3}
