The answer is -: 2


_____________________________

Step by Step Explanation-:

The laws that we had applied are -:

1) (a^m x a^n ) = a^m +n

2) (a^m ÷ a^n) ⇒ a ^m-n

Given ,

(2⁴×2⁵)÷2⁸

To evaluate-:

(2⁴×2⁵)÷2⁸

First ,


According to the BODMAS


First , We will solve the brackets


The law which we are going to apply-:


(a^m x a^n ) = a^m +n


⇒ (2^4 x 2^5) ÷ 2^8


⇒(2^4 + 5) ÷ 2^8


⇒ (2^9) ÷ 2^8

Now second law that we are going to


apply is -:

(a^m ÷ a^n)

⇒ a ^m-n


⇒ 2^9 ÷ 2^8


⇒ 2^9-8


⇒ 2^1


⇒ 2


Hence ,


⇒ (2^4 x 2^5) ÷ 2^8


= 2


The answer is -: 2
