The new definition calculation (a △ B = 10A power X 10B power) is listed as 3 △ 4 = 10 ^ 3 * 10 ^ 4 = 10 ^ 7 (1) Find the value of 3 △ 7 (2) Is (m △ n) △ P equal to m △ n △ p? Please explain why

A △ B = 10 (a + b) power, so (1) is the 10th power of 10 (2)) (m △ n) △ P = 10 (M + n) power △ P = 10 (10 (M + n) power + P) m △ n (P) = 10 (10 (10 (n + P) power + m) so it is not equal. It seems a bit troublesome. In fact, it is not troublesome to write it by comparison, because typing with computer may
