A new operation is defined, which stipulates: a * b = 4AB, for example, 2 * 3 = 4 × 2 × 3 (1) find the value of - 4 * 5 (2) find the value of - 2 * (- 3 * 4) Detailed process

A new operation is defined, which stipulates: a * b = 4AB, for example, 2 * 3 = 4 × 2 × 3 (1) find the value of - 4 * 5 (2) find the value of - 2 * (- 3 * 4) Detailed process

A new operation is defined, which stipulates: a * b = 4AB, such as 2 * 3 = 4 × 2 × 3 (1) find the value of - 4 * 5 = 4 × (- 4) × 5 = - 16 × 5 = - 80; (2) find the value of - 2 * (- 3 * 4) = - 2 * (4 × (- 3) × 4) = - 2 * (- 48) = 4 × (- 2) × (- 48) = 384; I'm glad to answer for you, skyhunter 002 will answer for you if there is anything unclear about this problem
