Applications from the microeconomic approach

Consumer theory(When you derive partially with respect to "u" you should take "v" as constant, and when you partially derive with respect to "v", "u" will be taken as constant. Example ?? / ? = 10?)

Applications from the microeconomic approach Consumer theory 1) y = 5u2 + 8v the function of the total joy (y) obtained by the consumer for the consumption of units of good "u" and good "y". Find the partial derivatives dy/du, y dy/dv Interpret "dy / du, y dy / dv" in the microeconomic context of marginal utility What good brings greater joy to the consumer with its consumption? (When partially derived with respect to "u" you should take "v" as constant, and when partially derived with respect to "v", "u" will be taken as constant. Example dy / du = 10w)
