Question 1 Express the following in exponential form: (i) 6 × 6 × 6 × 6Since 6 is multiplying four times Thus, 6 × 6 × 6 × 6 = 64 Question 1 Express the following in exponential form: (ii) y × ySince y is multiplying two times Thus, y × y = y2 Question 1 Express the following in exponential form: (iii) b × b × b × b Since b is multiplying four times Thus, b × b × b × b = b4 Question 1 Express the following in exponential form: (iv) 5 × 5 × 7 × 7 × 7Here, we count 5 and 7 separately Since 5 is multiplying two times 7 is multiplying three times Thus, 5 × 5 × 7 × 7 × 7 = 52 × 73 Question 1 Express the following in exponential form: (v) 2 × 2 × a × a Here, we count 2 and a separately Since 2 is multiplying two times a is multiplying two times Thus, 2 × 2 × a × a = 22 × a2 = (2 × a)2 = (2a)2 Question 1 Express the following in exponential form: (vi) a × a × a × c × c × c × c × dHere, we count a, c and d separately Since a is multiplying three times c is multiplying four times d is multiplying one time Thus, a × a × a × c × c × c × c × d = a3 × c4 × d
