Se considera proportia x supra 14 = 0,3 supra y . calculati:
A) 10xy - 2 la puterea 5
B) 10 la puterea 2 xy + 7
C) 2 la puterea 3 xy + 3 la puterea 2

Answer 1

x/14= 3/10y => 10xy= 42 => xy= 42/10

A. 10xy - 2 la puterea 5 = 42 - 32 =10
B. 10 la puterea 2xy +7 = 10 la puterea 42/5 +7
C. 2 la puterea 3xy + 3² = 2 la puterea 126/10 +9
