Question

what is x=1, 2, and 3 in the equation?

Y=5^(-x/2)

Answer 1

first put x=1 then find the value of y by simplifying. and then put x=2,3 for other values of y.

Answer 2

here x is power of 5 if u put x=1 then it wil become 5^(-1/2) which will then be written as 1/5^1/2 or\[1/\sqrt{5}\] then solve it.
