9power5/2-3.(5)power0-1/81 power-1/2​

Answer 1

Answer: 231

Explanation : So the first term is 9⁵/² which can be written as (9¹/²)⁵ ie 3⁵. (point 1)

second term is 3*(5)⁰ which is 3*(1) ie 3.(point 2)

third term is (1/81) raise to -¹/² which can be written as (81)¹/² ie 9.(point 3)

So then solve the question,

3⁵ - 3 - 9

= 243-12

= 231
