Question

01. Resolva as potências a seguir:

a) 11² =
b) (−5)³ =
c) (1/4)²
d) 25¹ =


​

Answer 1

→ Cálculo :

A) 11² = 11 · 11 = 121

B) ( - 5 )³ = -5³ = -( 5 · 5 · 5 ) = -125

C) (1/4)² = 1²/4² = 1/16

D) 25¹ = 25

Answer 2

Olá ! (^_-)

$\large \sf \displaystyle{ \sf \: a)11 {}^{2} = 11 \cdot11 = { \boxed{ \red{121}}}}$

--------------------------------------------

$\large \sf \displaystyle{ \sf \: b)( - 5) {}^{3} = - (5 \cdot 5 \cdot 5 ) = { \boxed{ \red{ - 125}}}}$

--------------------------------------------

$\large \sf \displaystyle{ \sf \:c){\left ( \dfrac{1}{4} \right ) ^{2} } = \frac{1 {}^{2} }{ 4{}^{2} } ={ \frac{1 \times 1}{4 \times 4} } = { \boxed{ \red{ \frac{1}{16} }}}}$

--------------------------------------------

$\large \sf \displaystyle{ \sf \: d)25 {}^{1} = { \boxed{ \red{ 25}}}}$

--------------------------------------------
