Answer: a)2²a² b)5²×7³ Step-by-step explanation: just see how many times the same number reapers and write down the powers Reply

Answer: a)4a² b)5²+7³ Step-by-step explanation: a) Since it is 2×2, it will be 4 and a×a will be a² and hence the exponential form is 4a² b) 5×5 will give 5² and 7×7×7 is 7³ and hence it is 5²+7³ Reply

Answer:a)2²a²

b)5²×7³

Answer:a)4a²

b)5²+7³

Step-by-step explanation:a) Since it is 2×2, it will be 4 and a×a will be a² and hence the exponential form is 4a²

b) 5×5 will give 5² and 7×7×7 is 7³ and hence it is 5²+7³
