Question

Q-1 express the following in exponential form :
a) 2×2×a×a
=
b)5×5×7×7×7
=​

Answer 1

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

Answer 2

Answer:

a)2²a²

b)5²×7³

Step-by-step explanation:

just see how many times the same number reapers and write down the powers
