Question

(50-2) ^3 ... expand.... pls solve step by step....pls answer asap​

Answer 1

Answer:

the correct answer is 110592

Step-by-step explanation:

  expanding $( 50 - 2) ^{3}$ ,

$( 50-2) ^{3} = 48^{3}$  here we can calculate it like  48× 48 ×48 but

calculating directly will take time, may be some mistakes will occur that's why will use the following formula for calculation

calculating with 50 , 2 are more convenient than calculating with 48  

  = $( a -b)^{3} = a^{3} -b^{3} - 3ab (a-b)$

  $=50^{3} -2^{3} - 3(50) (2) (50-2)\\=125000- 8 - 3(100)(48)\\=125000- 14408\\= 110592$
