Express the following in exponential notation :(i) 343 / 512 (ii) -32 / 243 (iii) -1 / 128 (iv) 729 / 64

Question

KnowledgeBoat · Accepted Answer

(i) We have: 343 = 7 x 7 x 7 = 73 512 = 8 x 8 x 8 = 83 ∴ Hence, the answer is (ii) We have: -32 = (-2) x (-2) x (-2) x (-2) x (-2) = (-2)5 243 = 3 x 3 x 3 x 3 x 3 = 35 ∴ Hence, the answer is (iii) We have denominator 128: ∴ 128 = 2 x 2 x 2 x 2 x 2 x 2 x 2 = 27 -1 = (-1)7 (Since any odd power of -1 is -1) ∴ Hence, the answer is (iv) We have: 729 = 3 x 3 x 3 x 3 x 3 x 3 = 36 64 = 2 x 2 x 2 x 2 x 2 x 2 = 26 ∴ Hence, the answer is
