Question

Stiind ca y=9,determinați produsul p=(y+5)×(2y-4)×(3y+3)

Answer 1

Răspuns: $\red{\underline{\bf p = 5~880}}$

$\bf y = 9$

$\bf p = (y +5)\cdot (2y-4)\cdot (3y+3)$

$\bf p = (9 +5)\cdot (2\cdot 9-4)\cdot (3\cdot 9+3)$

$\bf p = 14\cdot (18-4)\cdot (27+3)$

$\bf p = 14\cdot 14\cdot 30$

$\bf p = 196\cdot 30$

$\red{\boxed{\bf ~p = 5~880~}}$
