Question 18363: Hi,
Can anyone explain the mathematical rule behind this derivation:
x^2 is proportional to Y^3
so
x is proportional to Y^3/2.
In the above rule the exponent 2 is being moved from one side of the derivation to the other and becomes 3/2.How?
Answer by Earlsdon(6294) (Show Source): You can put this solution on YOUR website!
You can write proportions as an equation if you use an arbitrary constant of proportionality (k).
Take the square root of both sides.
Simplify; Multiply the exponents.

Therefore:
is proportional to
