Question

2. In an operation * is defined such that a * b = a + b - a * b. Find (b) (-4) * 5 (c) (-4) * (-5) (a) 4 * (-5)​

Answer 1

Answer:

Find the prime factorization of 250

250 = 2 × 5 × 5 × 5Find the prime factorization of 375

375 = 3 × 5 × 5 × 5Multiply each factor the greater

number of times it occurs in steps i) or ii) above to find the LCM:

LCM = 2 × 3 × 5 × 5 × 5LCM = 750
