Sir the numbers under the root have 10 digits ,and in the cat calculator we can insert a maximum of 9 digits , can you please show the approximations here in a detailed way . Thank you .
Hi From observation , you can write 3600840049 as (60000 +7)^2 Similarly you can write 6407522209 as (80000+Â 47)^2Â You can observe this by simply looking at the digits in the end - 2207 and 49 , they are squares of 47 and 7. Hope this helps!
