Answer:
(√9)^2x-1/2 = 1/81
3^2x-1/2 = 1/(3)⁴. (as √9 = 3)
3^2x-1/2 = 3^-⁴. (as 1/a^m = a^-m)
as base are equal exponents are equal
so 3 gets cancelled out
2x-1/2 = -4
(4x-1)/2 = -4
4x-1 = -8
x = -7/4
hope this helps

Answer:
Step-by-step explanation:
We want to find the equation of an ellipse with foci at (0,4) and (0,-4), and vertices at (0,6), (0,-6).
Since the major axis is on the y-axis the equation of this ellipse which is centered at the origin is given by:
Using we obtain:
Hence the required equation is
