x+(1/2x)
=>x+x/2x=2
=>x+1/2=2
=>x=2-1/2
=>x=(4-1)/2
=>x=3/2
Now,
8x^2 + (1/x^3)
=>8×3/2^2 + (1/(3/2^3))
=>8×9/4 + (1/(27/8))
=>18 + 8/27
=>(486+8)/27
=>494/27
=>18.30
=>x+x/2x=2
=>x+1/2=2
=>x=2-1/2
=>x=(4-1)/2
=>x=3/2
Now,
8x^2 + (1/x^3)
=>8×3/2^2 + (1/(3/2^3))
=>8×9/4 + (1/(27/8))
=>18 + 8/27
=>(486+8)/27
=>494/27
=>18.30
