---> 800/64= (2^3*10^2)/(2^3 * 2^3).
---> 1296/36=(6^2*6^2)/(6^2),
--> cancel the similar terms and next we get.
---> (10^2)*(6^2)/(2^3) = 3600/8 = 450.
---> 1296/36=(6^2*6^2)/(6^2),
--> cancel the similar terms and next we get.
---> (10^2)*(6^2)/(2^3) = 3600/8 = 450.

800/64 *1296/36.
(2^3*10^2/2^6) * (6^4/6^2).
By solving like this we get easily the answer.
10^2*6^2/2^3.
3600/8=450.
(2^3*10^2/2^6) * (6^4/6^2).
By solving like this we get easily the answer.
10^2*6^2/2^3.
3600/8=450.

Hi,
800/65=12.5
1296/36=36.
Then 12.5/36 is 450.
So there not given 450.
So the answer is none of these.
800/65=12.5
1296/36=36.
Then 12.5/36 is 450.
So there not given 450.
So the answer is none of these.

-->100/8*216/6.
-->25/2*36.
-->25*18.
-->450.
-->100/8*216/6.
-->25/2*36.
-->25*18.

--> (8*100)/(8*8) = 12.5.
--> (36*36)/36 = 36.
--> 36*12.5 = 450.
--> (36*36)/36 = 36.
--> 36*12.5 = 450.

800/64 * 1296/36,
Soltn: =100*8/64 * 1296/36,
= 100 *1296/288,
= 450.
Soltn: =100*8/64 * 1296/36,
= 100 *1296/288,
= 450.
