If you would like to know what is the value of 54 - 4 * a^2 + 3 * b^3 when a = - 2 and b = 4, you can calculate this using the following steps:

54 - 4 * a^2 + 3 * b^3 = 54 - 4 * (-2) ^2 + 3 * 4^3 = 54 - 4 * 4 + 3 * 64 = 54 - 16 + 192 = 230

If you would like to know what is the value of 54 - 4 * a^2 - 3 * b^3 when a = - 2 and b = 4, you can calculate this using the following steps:

54 - 4 * a^2 - 3 * b^3 = 54 - 4 * (-2) ^2 - 3 * 4^3 = 54 - 4 * 4 - 3 * 64 = 54 - 16 - 192 = - 154
