Question

3×[5^9:5^8+(3^4-2^4×5)^2015+8^7:16^5

Va rooog mult dau Coronita am nevoie e pt maine

Answer 1

3 x [ 5⁹ : 5⁸ + ( 3⁴ - 2⁴ x 5 ) ²⁰¹⁵ + 8⁷ : 16⁵]  = 24

= 3 x [ 5 ⁽ ⁹ ⁻ ⁸ ⁾  + ( 81 - 16 x 5 )²⁰¹⁵ + ( 2³ ) ⁷ : ( 2⁴ )⁵ ] =

= 3 x [ 5¹ + ( 81 - 80 )²⁰¹⁵  + 2²¹ : 2²⁰ ] =

= 3 x ( 5 + 1²⁰¹⁵ + 2 ⁽ ²¹ ⁻ ²⁰ ⁾ ) =

= 3 x ( 5 + 1 + 2¹ ) =

= 3 x 8 =

= 24
