Express each of the following in exponential notation :(i) (5/21)^3 x (5/21)^8 (ii) (-7/3)^11 x (-7/3)^13 (iii) (13/43)^7 / (13/43)^2 (iv) (-16/35)^16 / (-16/35)^3 (v) (-7/15)^12 / (-7/15)^15 (vi) (1/24)^13 / (1/24)^16

Question

KnowledgeBoat · Accepted Answer

(i) Using the multiplication rule, we add the exponents: 3 + 8 = 11. Hence, the answer is (ii) Using the multiplication rule, we add the exponents: 11 + 13 = 24. Hence, the answer is (iii) Using the division rule, we subtract the exponents: 7 - 2 = 5. Hence, the answer is (iv) Using the division rule, we subtract the exponents: 16 - 3 = 13. Hence, the answer is (v) Using the division rule, we subtract the exponents: 12 - 15 = -3. Hence, the answer is (vi) Using the division rule, we subtract the exponents: 13 - 16 = -3. Hence, the answer is 243
