choose the odd one: a)144 b)168 c)196 d)256 give reason
Here is a hint...
12 x 12 = 144
Look at the other answers and see what comes to mind...
168
To determine the odd one out from the given options, we need to compare them and look for any distinctive pattern or property that sets one apart from the rest. Here is a step-by-step analysis of the options:
Option a) 144: 144 can be expressed as 12^2 (12 raised to the power of 2), which means that it is a perfect square.
Option b) 168: 168 is not a perfect square, but it could still share some common pattern with the other options, so let's keep it for now.
Option c) 196: Similarly to 144, 196 can be expressed as 14^2, indicating that it is also a perfect square.
Option d) 256: Like 144 and 196, 256 can be written as 16^2 and is thus a perfect square.
By evaluating each option, we can see that all of them are perfect squares except for option b) 168. Therefore, the answer is b) 168. The reason it is the odd one out is that it is not a perfect square, unlike the other options.
