Why is it that if the x power of a is equal to the W power of 70, the 1 / W power of a is equal to the 1 / x power of 70

Why is it that if the x power of a is equal to the W power of 70, the 1 / W power of a is equal to the 1 / x power of 70

Take the logarithm of the x power of a and the W power of 70
x ln A=w ln W
then
ln A ÷ w = ln W ÷ x
This gives a 1 / W power of a to the 1 / x power of 70

What figure does the sum of the squares of X and y equal to Z

It's a paraboloid with a vertex at the origin

What figure does the square of X + the square of y equal to 0 represent

x²+y²=0
Then x = y = 0
The origin is X & sup2; + Y & sup2; = 0
