Question

(1/4)²-3(8)⅔*1+(9/16)½​

Answer 1

Answer:

$\left(\frac{1}{4}\right)^{2} - 3(8)^{\frac{2}{3}} + \left(\frac{9}{16}\right)^{\frac{1}{2}}$

$= \left(\frac{1}{4}\right)^{2} - 3(2^{3})^{\frac{2}{3}} + \left( \frac{3^{2}}{4^{2}}\right)^{\frac{1}{2}}$

$= \frac{1}{16} - 3 \times 2^{2} + \frac{ 3}{4}\\= \frac{1}{16} - 12 + \frac{3}{4}\\= \frac{1-192+12}{16} \\= \frac{-179}{16}$
