a) 5⁶ : 5² =
b) x⁷. x⁸=
c) 2⁴ . 2 . 2⁹ =
d) x⁵ : x³ . x =
e) m⁷ . m⁰ . m⁵ =
f) a . a² . a =
g) (+5)⁷ : (+5)² =
h) (+6)² . (+6)³ =

Answer 1

Resposta:

a) $5^{4\\}$

b) $x^{15}$

c) $2^{14}$

d) $x^{3}$

e) $m^{12}$

f) $a^{4}$

g) $(+5)^{5}$

h) $(+6)^{5}$

Answer 2

a) 5⁶ : 5² = 5⁶-² = 5⁴

b) x⁷ . x⁸ = x⁷+⁸ = x¹⁵

c) 2⁴ . 2 . 2⁹ = 2⁵ . 2⁹ = 2¹⁴

d) x⁵ : x³ . x = x⁵ . x-³ . x = x⁵ . x-³ . x¹ = x⁵-³+¹ = x³

e) m⁷ . m⁰ . m⁵ = m⁷ . 1m⁵ = m⁷ . m⁵ = m¹²

f) a . a² . a = a¹ . a² . a¹ = a¹+²+¹ = a⁴

g) ( +5 )⁷ : ( +5 )² = 5⁷-² = 5⁶

h) ( +6 )² . ( +6 )³ = 6²+³ = 6⁵
