Expand:

log7= 3sqrtx / x^2y

To expand the equation "log7= 3sqrtx / x^2y," we need to rearrange the equation and solve for the variables.

First, let's isolate the variable on one side of the equation. In this case, it is the variable "x."

1. Multiply both sides of the equation by "x^2y":
x^2y * log7 = 3sqrtx

2. Divide both sides of the equation by "3":
(x^2y * log7) / 3 = sqrtx

3. Square both sides of the equation to remove the square root:
[(x^2y * log7) / 3]^2 = x

Now, the expanded equation is:

x = [(x^2y * log7) / 3]^2

Note that we need to know the specific values of "x," "y," and "log7" to simplify the equation further.
