[7 power -1+(3/2)-1]-1 if any one will give me this right answer I will mark him as brainliest
with meathod. ​

Answer 1

Answer:

= [(7)-¹ + (3/2)-1]×-1

=. [(1/7)¹-3/2]×-1

=. [1/7-3/2]×-1

Iske aage shayad mujhe batane ki zaroorat nahi hai.

Answer 2

${\blue{{\sf{ {7}^{ - 1} + \frac{3}{2} - 1}}}} \\ {\green{{\sf{- 1 - 1 + \frac{3}{2} = - 2 + \frac{3}{2} = \frac{1}{2} \: }}}} \\ {\blue{{\sf{{7}^{ \frac{-1}{2} } = \frac{(1)}{(7)}^\frac{(1)}{(2)} \: }}}} \\{\red{{\sf{ \: = \frac{1}{ \sqrt{7 - 1} } }}}}$
