Answer 2

Answer:

77.622

Step-by-step explanation:

3(√125+√216)

3(√5cube+√6cube)

3(√5×5square+√6+6square)

3(5√5+6√6)

3[5(2.236)+6(2.449)]

3[11.180+14.694]

3(25.874)

77.622

well, that is my own calculation, slightly different from calculator. and, i also think you havent asked for actual decimal value, rather a simpler form..that must be 3[5√5+6√6]
