Question

Using proper identity find the value of 4.359 x 4.359 -1.641x1.641 / 4.359 - 1.641

Answer 1

Answer:

6.000

Step-by-step explanation:

( 4.359 ) * ( 4.359 ) - ( 1.641 ) * ( 1.641 ) / ( 4.359 ) - ( 1.641 )

You must be knowing...

${a}^{2} - {b}^{2} = (a - b) \times (a + b)$

so from above,

( 4.359 )² - ( 1.641 )² / ( 4.359 ) - ( 1.641 )

{ ( 4.359 ) - ( 1.641 ) } * { ( 4.359 ) + ( 1.641 ) } / ( 4.359 ) - ( 1.641 )

Cancelling { ( 4.359 ) - ( 1.641 ) } from numerator and denominator

we get,

( 4.359 ) + ( 1.641 )

= 6.000

= 6

It is your answer...
