Answer:
√x + 1/2√x = √3
2x + 1/2√x = √3
2x + 1 = 2√3x
2x = 2√3x - 1
x = 2√3x-1/2
x² + 1/16x² = ?
= (2√3x-1/2)² + 1/16(2√3x-1/2)²
= 12x²-1/4 + 1/16(12x²-1/4)
= 12x²-1/4 + 1/16(48x²-1/4)
= 12x²-1/4 + 1/4(48x²-1)
= (12x²-1)(48x²-1)+1/4(48x²-1)
= 216x²-48x²-12x²+1+1/192x²-1
= 216x²-60x²+2/192-1
= 164x²-2/192x²-1
= 82x²-1/192x²-1
Hence the value of x² + 1/16x² = 82x²-1/192x²-1.
