Exercise 13.1
Question 1:
Find the value of:
(i) 26 (ii) 93 (iii) 112 (iv) 54
Answer:
(i) 26 = 2 * 2 * 2 * 2 * 2 * 2 = 64
(ii) 93 = 9 * 9 * 9 = 729
(iii) 112 = 11 * 11 = 121
(iv) 54 = 5 * 5 * 5 * 5 = 625
Question 2:
Express the following in exponential form:
(i) 6 * 6 * 6 * 6 (ii) t * t (iii) b * b * b * b (iv) 5 * 5 * 7 * 7 * 7 (v) 2 * 2 * a * a
(vi) a * a * a * c * c * c * c * d
Answer:
(i) 6 * 6 * 6 * 6 = 64
(ii) t * t = t2
(iii) b * b * b * b = b4
(iv) 5 * 5 * 7 * 7 * 7 = 52 * 73
(v) 2 * 2 * a * a = 22 * a2
(vi) a * a * a * c * c * c * c * d = a3 * c4 * d
