g) ${ \frac{3}{5} }^{2} =$

h) ${( {7}^{2} )}^{10} =$
​

Answer 1

Resposta:

1) a) 3¹²

b) 5⁵

c) a⁵

d) 10⁵

e) 2⁴

f) x⁸•y⁸

g) 3²/5²

h) 7²⁰

Cálculo:

1) a) 3⁵•3²•3•3⁴ = 3^⁵+²+¹+⁴ = 3¹²

b) 5⁷•5^-² = 5^⁷+(-²) = 5^⁷-² = 5⁵

c) a²•a³•a⁰ = a²•a³•1 = a²•a³ = a^²+³ = a⁵

d) 10⁷÷10² = 10^⁷-² = 10⁵

e) 2⁵/2 = 2^⁵-¹ = 2⁴

f) (x•y)⁸ = x⁸•y⁸

g) (3/5)² = 3²/5²

h) (7²)¹⁰ = 7^²•¹⁰ = 7²⁰
