Question

Va rog am nevoie urgent de raspunsuri

Answer 1

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

$a ^{n} \times a ^{m} = a ^{m + n}$
Acum...sa revenim la exercițiul tau...

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

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

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