Here is your answer ❤

Given : 3a-2b

Find : (3a-2b) ^3

Solution:

${(3a - 2b)}^{3} \\ we \: know \: that \: {(a - b)}^{3} = {a}^{3} + {b}^{3} - 3 {a}^{2} b - 3 {b}^{2} a \\ so \: here \\ {3a}^{3} + {2b}^{3} - 3 {(2b)}^{2} (3a) - 3 {(3a)}^{2} (2b) \\ 27 {a}^{3} + 8 {b}^{3} - 18 {b}^{2}a - 54 {a}^{2} b$
