Question

quanto é a raiz de x elevado a 5​

Answer 1

Resposta:

$\displaystyle \sqrt{x^5} =x^2.\sqrt{x}$

Explicação passo-a-passo:

$\displaystyle \sqrt{x^5} =\sqrt{x^{(4+1)}} =\sqrt{x^4.x^1} =x^{\frac{4}{2}}.x^{\frac{1}{2} }=x^2.x^{\frac{1}{2} }=x^2.\sqrt{x}$

Propriedades:

$\displaystyle (a^{m})^{n}=a^{m.n}\\\\\sqrt[n]{x^m} =x^{\frac{m}{n} }\\\\a^{m}a^{n}=a^{m+n}\\\\\frac{a^{m}}{a^{n}}=a^{m-n} \\\\a^{0}=1\\\\a^{1}=a$
