Q. 76

Express the following in exponential form:

(a) 3 × 3 × 3 × a × a × a ×a

(b) a × a × b × b × b × c × c × c × c

(c) s × s × t × t × s × s × t

Answer :

(a) Number of terms of 3 = 3


Number of terms of a = 4


3 × 3 × 3 × a × a × a ×a = 33a4


(b) Number of terms of a = 2


Number of terms of b = 3


Number of terms of c = 4


a × a × b × b × b × c × c × c × c = a2b3c4


(c) Number of terms of s = 4


Number of terms of t = 3


s × s × t × t × s × s × t = s4t3
