Answer 1

Resposta:

1- L²= 1024

L= √1024

L= 32 m

P= 32+32+32+32= 128 m

LETRA E

2- Volume → 216 cm³  

V = a³  

216 = a³  

a = ∛216  ← Raiz cúbica ; 6 . 6 . 6 = 216

a = 6 cm

LETRA B

3- a) $3^{\frac{2}{5} }$

b) $\sqrt[2]{8^{7} }$

c) $5^{\frac{3}{7} }$

d) $\sqrt[2]{2^{3} }$

e) $7^{\frac{4}{9} }$

f) $2^{\frac{2}{6} }$

g) $\sqrt[4]{10^{5} }$

h) $27^{3}$

i) $3^{\frac{4}{12} }$

j) $9^{\frac{8}{4} }$

4- a) 2.2.3.3.3.5 = 2².3³.5

b) 2 . 2 . 2 . 3 . 3 . 3 . 3 . 5 . 5 = $2^{3} . 3 ^{4} . 5^{2}$

c) 2 . 2 . 2 . 2 . 2 . 2 . 2 . 2 . 2 . 2  = $2^{10}$

d) 2 . 2 . 2 . 2 . 7 . 7 . 11 . 11  = $2^{4} . 7^{2} . 11^{2}$

5- a) 35

b) $23^{2}$

c) 11

d) $2^{3} 3$
