Q.3:Find the value of: (i) \( 2 ^ { 6 } \) (ii) \( 9 ^ { 3 } \) (iii) \( 11 ^ { 2 } \) (iv) \( 5 ^ { 4 } \)

Ans :(i) \( 2 ^ { 6 } = 2 \times 2 \times 2 \times 2 \times 2 \times 2 = 64 \) (ii) \( 9 ^ { 3 } = 9 \times 9 \times 9 = 729 \) (iii) \( 11 ^ { 2 } = 11 \times 11 = 121 \) (iv) \( 5 ^ { 4 } = 5 \times 5 \times 5 \times 5 = 625 \)

Q.4: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

Ans :(i) \( 6 \times 6 \times 6 \times 6 = 6 ^ { 4 } \) (ii) \( t \times t = t ^ { 2 } \) (iii) \( b \times b \times b \times b = b ^ { 4 } \) (iv) \( 5 \times 5 \times 7 \times 7 \times 7 = 5 ^ { 2 } \times 7 ^ { 3 } \) (v) \( 2 \times 2 \times a \times a = 2 ^ { 2 } \times a ^ { 2 } \) (vi) \( a \times a \times a \times c \times c \times c \times c \times d = a ^ { 3 } c ^ { 4 } d \)

Q.5:Express each of the following numbers using exponential notation: (i) 512 (ii) 343 (iii) 729 (iv) 3125

Ans :(i) \( 512 = 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 = 2 ^ { 9 } \) (ii) \( 343 = 7 \times 7 \times 7 = 7 ^ { 3 } \) (iii) \( 729 = 3 \times 3 \times 3 \times 3 \times 3 \times 3 = 3 ^ { 6 } \) (iv) \( 3125 = 5 \times 5 \times 5 \times 5 \times 5 = 5 ^ { 5 } \)
