Va Rog Am Nevoie Urgent De Raspunsuri class=

Răspuns :

In primul rand,trebuie sa stii ca la puteri,la înmulțiri se efectueaza adunare la exponent(daca baza este aceeasi).De exemplu:

[tex]a ^{n} \times a ^{m} = a ^{m + n} [/tex]
Acum...sa revenim la exercițiul tau...

a)
[tex]2 ^{5} \times 2 ^{32} = 2 ^{37} [/tex]
b)
[tex]3 ^{18} \times 3 ^{46} = 3^{64} [/tex]
c)
[tex]8 ^{42} \times 8^{36} = 8^{78} [/tex]

d)
[tex]15^{1003} \times 15^{203} = 15 ^{1206} [/tex]
e)
[tex]3 ^{48} \times 3 ^{13} \times 3 ^{41} = 3 ^{102} [/tex]
f)
[tex]4 ^{63} \times 4 ^{2} = 4 ^{65} [/tex]
g)
[tex]7 ^{45} \times 7 ^{57} = 7^{102} [/tex]
h)
[tex]6 ^{49} \times 6 ^{98} = 6^{147} [/tex]
i)
[tex]27 ^{453} \times 27 ^{527} = 27 ^{980} [/tex]
j)
[tex]2^{2005} \times 2 ^{1} \times 2 ^{0} = 2 ^{2006} [/tex]
Deoarece:
[tex]2 ^{0} = 1 \\ 2 ^{1} = 2 \\ 2 \times 1 = 2 \\ 2 ^{2005} \times 2 = 2 ^{2006} [/tex]
k)
[tex]11 ^{3} \times 11 ^{10} = 11^{13} [/tex]

l)
[tex]17 ^{0} \times 17^{49} = 17 ^{49} [/tex]
Deoarece:
[tex]17 ^{0} = 1 \\ 1 \times 17 ^{49} = 17 ^{49} [/tex]
Sper ca te-am ajutat...
