Answer 1

Answer:

$93 \frac{2}{3}$

Step-by-step explanation:

As the equation is,

${9}^{0} + {9}^{ - 1} + {9}^{ - 2} + {9}^{ \frac{1}{2} } - {9}^{ \frac{ - 1}{2} }$

$= (1) + ( \frac{1}{9} ) + ( \frac{1}{81} ) + (3) - ( \frac{1}{3} )$

$= \frac{81 + 9 + 1 + 243 - 27}{81}$

$= \frac{91 + 216}{81}$

$= 93 \frac{2}{3}$

which is your answer....
