I am using solve function in CAS.

This is the function that i have inputted:

solve((18*log10((12*(2*x+3*x^2)/(2+2*√(10)*x)/0.4))*√(((2*x+3*x^2)/(2+2*√(10)*x))*0.03)*(2*x+3*x^2)-15) = 0,x)

The answer I am given is: [[]]

Similarly when I input:

solve(((2*x+x^2)^(5/3)*√(3/100)/(0.025*(2+2*√(2)*x)^(2/3))) = 15,x)

The answer I am given is: {}

A normal CASIO fx-991ZA PLUS is able to solve for x in this equation, but I am struggling to understand why the HP Prime can't?

Assistance willl be gretaly appreciated!
