Value of is

The above question can be written as follows:

Again we have another law of indices which is as follows:

a^m ÷ aⁿ = a ^(m-n)

Here in the question,

For first part,

a = 10

m = 22

n = 20

∴ m – n = 22 – 20

= 2

For second part,

a = 10

m = 20

n = 20

∴ m – n = 20 – 20

= 0

We have the law of Indices as follows:

a⁰ = 1

Where a = any integer

So the correct answer is C.
