Problem with plotting

So I need to plot this function:

Y(x) = 170 *sin⁡[2 *arctan [[[-x^[4] + 340*x^[3] - 35150*x^[2] + 1062500*x + 3194375]^[1/2] - 2400]/[x^[2] - 290* x + 20525]]] + 20 

and i tried to do it like this

Plot    [170 * sin⁡[2 * arctan [[[-x^[4] + 340*x^[3] - 35150*x^[2] + 1062500*x + 3194375]^[1/2] - 2400]/[x^[2] - 290* x + 20525]]] + 20, {x, 0, 10}] 

but i keep getting syntax error:

Syntax::sntxb: Expression cannot begin with "[[x^[4]+340x^[3]-35150x^[2]+1062500x+3194375]^[1/2]-2400]/[x^[2]-290x+20525]"

Can anyone please help?
