Q.2 Exress 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) \( 6 × 6 × 6 × 6 = 6^3 \)
(ii)\( t × t = t^2 \)
(iii) \( b × b × b × b = b^4 \)
(iv) \(5 × 5× 7 × 7 × 7 = 5^2 × 7^3 = 5^2 · 7^3\)
(v) \(2 × 2 × a × a = 2^2 × a^2 = 2^2 · a^2 \)
(vi)\( a × a ×a × c × c × c × c × d = a^3 × c^4 × d = a^3 · c^4 · d \)
