So here according to the question, we have we have 2 raised to power 56 keys 2 raised to power 56 keys and computer can check computer can check 10 raised to power 10 keys 10 raised to power 10 keys per second.
00:26
Okay.
00:27
So this has been given to us in the question.
00:29
So according to the question, the keys checked in one second are 10 raised to power 10 keys.
00:37
Okay.
00:38
So if we talk about the time in which one key is checked, so by unitary method, it can be found out 1 upon 10 raised to power 10 seconds.
00:48
Okay.
00:49
So this is the time in which one key can be checked.
00:53
So if we talk about 2 raised to power 56 keys, so by unitary method, we will multiply the time with 2 raised to power 56.
01:00
Okay.
01:01
So 2 raised to power 56 upon 10 raised to power 10 seconds.
01:04
This will be the time.
01:05
Okay.
01:06
So if we convert it, we convert this seconds into days.
01:11
So what will we do here? we know one minute has 60 seconds.
01:15
Okay.
01:15
So first we will divide by 60.
01:19
So it will be in minutes.
01:20
Then we will divide in 60 again.
01:24
So it will be in hours...
