Prove that an integer is divisible by 4 if and only if the number formed by its tens and units digits is divisible by 4.

Kindly refer to below section.

Step-by-step explanation:

Any number can be represented as:

For example a number 78332 can be represented as:

Let any number be and the number formed by its tens and units digits is divisible by 4.

i.e. is divisible by 4.

Now, the number can be written as:

Therefore, is also divisible by 4.

Hence, proved that an integer is divisible by 4 if and only if the number formed by its tens and units digits is divisible by 4.

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
