QQQ M 1 8

**Solution:**

(i) 4 × 6 = 24

P = 7

74 × 6 = 444

(ii) M + 1 = 8

M = 7

L + M = 1

L = 4

2 + L + 1 = 7

L = 4

**✦ Try This: **Find the value of the letters in each of the following: (i) aa × aa × aa = abba, (ii) 2LL+ LL2 = 5M5

(i) 11 × 11 × 11 = 1331; a = 1 and b = 3

(ii) L + 2 = 5

L = 3

M = L + L = 3 + 3 = 6
