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
