Question

4- Utilizando a potenciação e suas propriedades, calcule:


A) 4²=
B) 4³=
C) 2⁴=
D) 2³. 2⁴=
E) 3². 3²=
F) 2⁶. 2⁴=
G) 2⁷. 2³=
H) 3⁹. 3⁹=

​

Answer 1

a) 4² = 4 × 4 = 16

b) 4³ = 4 × 4 × 4 = 64

c) 2⁴ = 2 × 2 × 2 × 2 = 16

d)

${2}^{3} \times {2}^{4} = {2}^{3 + 4} = {2}^{7} = 128$

e)

${3}^{2} \times {3}^{2} = {3}^{2 + 2} = {3}^{4} = 81$

f)

${2}^{6} \times {2}^{4} = {2}^{6 + 4} = {2}^{10} = 1024$

g)

${2}^{7} \times {2}^{3} = {2}^{7 + 3} = {2}^{10} = 1024$

h)

${3}^{9} \times {3}^{9} = {3}^{9 + 9} = {3}^{18} = 387420489$
