Question

(4+8+12+....+8000):(2+4+6+8+....+4000)+(3^54+3^53+3^52):3^52. ^ înseamnă la puterea

Answer 1

( 4 + 8 + 12 +.....+ 8 000 ) : ( 2 + 4 + 6 + 8 + .... + 4 000 ) + ( 3⁵⁴ + 3⁵³ + 3⁵² ) : 3⁵² = 15

= 4 × ( 1 + 2 + 3 + .... + 2 000 ) : 2 × ( 1 + 2 + 3 + ..... + 2 000 ) + 3⁵² × ( 3² +3+1 ) : 3⁵² =

= 2 + ( 9 + 4 ) =

= 2 + 13 =

= 15

Answer 2

(4 + 8 + ..+ 8000) : (2 + 4 + ..+4000) + (3⁵⁴+3⁵³+3⁵²) : 3⁵² =

= 2(2 + 4 + .. + 4000) : (2 + 4 + .. + 4000) + 3⁵²(3² + 3¹ + 1) : 3⁵²

= 2 + (9 + 3 + 1)

= 2 + 13

= 15
