Question

[(6×5^10-5^10)^3÷25^15-47^0]×10^3

Answer 1

[( 6 × 5^10 - 5^10 )³ ÷ 25^15 - 47^0 ] × 10³

[( 5 × 5^10 )³ : 25^15 - 47^0 ] × 10³

[( 5^11 )³ : 5^30 - 1 ] × 10³

( 5^33 : 5^30 - 1 ) × 10³

( 5^33-30 - 1 ) × 10³  = ( 5³ - 1 ) × 10³ = 50³ - 10³

= ( 5 × 10 )³ - 10³ = 5³ × 10³ - 10³ =

= 5³ × 2³ × ( 5³ - 1 ) =

= 125 × 8( 125 - 1 ) = 125 × 8 × 124 = 1000 × 124 = 124000
