Fine unit number // इकाई का अंक ज्ञात करना

To know the unit's points, the first ones were given the equation, and then after inspecting, start sorting, to find the number of the unit, the number of mathematics is taken from the system.

Finding unit number in normal product

In order to know the unit number in the normal product, solve the process given below.

Unit of each term in the number take the number

If you get ten points in the product again, leaving it, then issue the number of the unit and multiply it further.

for example

$568\times 723\times 864$ Unit number

$8\times 3\times 4$
96 Unit number is 6

Finding unit number in exponential number

If the number of unit number 0 ,1 is 5 ,6

If the unit's number is 0,1, 5, 6, then its unit's number is the same
for example

$590^{111}$ unit number is 0

If the unit number is 3

If the number of the unit is 3, $3^{4}= 1$ then according to the solution

$353^{158} =3^{4)\frac{158}{4}}$

$( 3)^{4^{39+2}} = 3^{4)39}\times 3^{2}$

$1^{39}\times 9 = 9$ Answer is , 9

If the unit number is 9

If the unit has a score of 9, then if the power is equal to the unit's numeral 1 and 9 if it is odd

for example

$349^{241}$

The number of the unit is 214 as the odd number so the unit's number is 9

If the unit number is 7

If the number of the unit is 3, $3^{4}= 1$ then according to the solution

$3127^{173}$

$7^{4)173/4}$

$7^{4) 43+1} =7^{4)43}\times 7^{1} =1^{43}\times 7 = 7 Answer$
