Answer 1

Answer:

1

Step-by-step explanation:

$((3)^{-1} +(5)^{-1} +(7)^{-1} )^{0} \\\\(\frac{1}{3} +\frac{1}{5} +\frac{1}{7} )^{0} \\\\Taking LCM,\\\\(\frac{35+21+15}{105} )^{0} \\\\(\frac{71}{105} )^{0} \\\\1$

→ It is proven that any number or expression raised to the power of zero is always equal to 1.
