Question

a primera pamavra um certo e a primeira palavra da segunda lunha e determine

Answer 1

a=√1-11/25
a=√(25-11)/25
a=√13/25
a=√13/√25
a=√13/5

a²=√1-11/25
a=√√1-11/25
a=1-11/25
a=(25-13)/25
a=13/25

a³=√1-11/25
a=∛√1-11/25
a=∛√(25-11)/25
a=∛√13/25
a=raiz sexta de 13/25

Answer 2

$\sqrt{ 1 + \dfrac{11}{25}}$

mmc = 25

$\sqrt{ \dfrac{25 + 11}{25}} \\ \\ \\ \sqrt{ \dfrac{36}{25}} \\ \\ \\ \dfrac{ \sqrt{36}}{ \sqrt{25}} \\ \\ \\ => \dfrac{6}{5}$

=========

Determinar o valor de a

a = $\dfrac{6}{5}$

==========

Determinar o valor de a²

a² = $(\dfrac{6}{5} )^2 \ \ => \dfrac{36}{25}$

==========
Determinar o valor de a³

a³ = $(\dfrac{6}{5})^3 \ \ => \dfrac{216}{125}$
