para la fiesta del sabado pasado los chicos compraron 2 bidones con jugo ,uno de naranja y el otro de pomelo el de naranja tenia 72L y el de pomelo,60L .Se tomaron 2/3 del jugo de naranja y sobro 1/3 del bidon de pomelo ¿cuantos litros de jugo se tomaron en total?

Just a second zzz

1.   an exact solution requires a radical solution - no decimal approximation.2. (a)4x^3 = 756x^3 = 756/4 = 189x =   cube root of 189 =   5.74   to nearest hundredth answer(b)   189 = 3*3*3*7   so we can write the cube root of 189 as 3∛7 answerchecking (a) 4*(5.74^3 =   756.48   which is very close(b)   4* ((3∛3)^3   = 4*189   = 756   - spot on! 3. i would use solution b because the original question asked for an exact solution.
