Question

Va roggg e urgenttttt!!!!!!
Scrieti ca o putere cu exponent numar natural produsul de numere intregi :
a)(-4)•(-4)•(-4)•(-4)•(-4);
b)(-12)•(-12)•(-12)•…•(-12),20 de factori;
c)(+15)•(+15)•(+15)•…•(+15),2012 factori.

Answer 1

a) (-4)•(-4)•(-4)•(-4)•(-4) = (-4)⁵

b) (-12)•(-12)•(-12)•…•(-12), 20 de factori;

$\it \underbrace{\it(-12)\cdot(-12)\cdot(-12)\cdot\ ...\ \cdot(-12)}_{20\ factori} = (-12)^{20} = 12^{20}\ ( exponent \ par)$

c)

$\underbrace{\it(+15)\cdot(+15)\cdot(+15)\cdot\ ...\ \cdot(+15)}_{2012\ factori} = \it15^{2012}$

Answer 2

numeri exponentii si atunci vei avea la pct a) (-4)^5; la pct b) (-12)^20; la pct c) (15)^2012
