When there are variables with exponents on the bottom you have to subtract the ones on the bottom from the ones on the top. Then if the exponent is negative you have to flip it.
The numeric constant of variation is 100
Step-by-step explanation:
Direct proportion means that increase in one variable cause increase in other variable
Here,
It is given that
y varies directly as x
y∝x
when the proportionality symbol is removed a proportionality constant is introduced

Given that
y = 100 when x = 4
Putting the values

The numeric constant of variation is 100
