Question

(3^1008+3^1009+3^1010):(3^1006×13) va rog ajutatima !!​

Answer 1

Răspuns:

$= 9$

Explicație pas cu pas:

$\frac{3 {}^{1008} + {3}^{1009} + {3}^{1010} }{ {3}^{1006} \cdot13} = \frac{3 {}^{ \not1008} \cdot( 1 + 3 + {3}^{2} ) }{ {3}^{ \not1006} \cdot13 } = \frac{ {3}^{2} \cdot(1 + 3 + 9) }{13} = \frac{ 9 \cdot \not13}{ \not13} =\boxed{ 9}$
