a, \(\sqrt{1+x}-\sqrt{8-x}+\sqrt{\left(1+x\right)\left(8-x\right)}=3\)
b, \(\sqrt{3x^2+5x+8}-\sqrt{3x^2+5x+1}=1\)
c, \(2x^2+4x=\sqrt{\dfrac{x+3}{2}}\)
d, \(2\left(x^2-3x+2\right)=3\sqrt{x^3+8}\)
e, \(729x^4+8\sqrt{1-x^2}=36\)
f, \(7x^2-10x+14=5\sqrt{x^4+4}\)
g, \(x^3+3x^2-3\sqrt[3]{3x+5}=1-3x\)
h, \(\sqrt{4-3\sqrt{10-3x}}=x-2\)
