Question

Find the value of (1/4) - 2 – 3(8) 2/3(4)0 + (9/16) – 1/2 .​

Answer 1

¼ - 2 - 24 (8/3)(0) + 9/16 - ½ = -5/4 + 9/16

= 9/16 - 5/4 = (9-20)/16 = -11/16

Answer 2

SOLUTION :

$( { \frac{1}{4} })^{ - 2} - 3( {8})^{ \frac{2}{3} } ({4})^{0} + ({ \frac{9}{16} })^{ \frac{ - 1}{2} }$

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

$= 16 - 3 \times {2}^{2} + ({ \frac{3}{4} })^{ - 1}$

$= 16 - 12 + \frac{4}{3}$

$= 4 + \frac{4}{3}$

$= \frac{12 + 4}{3}$

$= \frac{16}{3}$

HOPES, IT'S HELPFUL TO YOU BRO. ^_^
