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 × c × c × c × c × d
(i) We have,
6 × 6 × 6 × 6
= 61+1+1+1
= 64
(ii) We have,
t × t
= t1+1
= t2
(iii) We have,
b × b × b × b
= b1+1+1+1
= b4
(iv) We have,
5 × 5 × 7 × 7 × 7
= 51+1 × 71+1+1
= 52 × 73
(v) We have,
2 × 2 × a × a
= 21+1 × a1+1
= 22 × a2
(vi) We have,
a × a × a × c × c × c × c × d
= a1+1+1 × c1+1+1+1 × d1
= a3 × c4 × d
