8.73x8.73x8.73+ 4.27 x 4.27 x 4.27
8.73 x 8.73-8.73 x 4.27 x +4.27 x 4.27​

Answer 1

Answer:

did you mean ( 8.73 x 8.73 x 8.73 + 4.27 x 4.27 x 4.27 ) / ( 8.73 x 8.73 - 8.73 x 4.27 + 4.27 x 4.27 ) ?

Step-by-step explanation:

Let a = 8.73 and b = 4.27

Then, given expression =( a3 + b3 ) / ( a2 - ab + b2 )

As we Know the Algebra formula,

a3 + b3 = (a + b) (a2 - ab + b2)

Apply the above algebra formula in given above expression,

= (a + b) (a2 - ab + b2) / ( a2 - ab + b2 )

= (a + b)

= 8.73 + 4.27 = 13
