Question

D) 1/4 la puterea 0 - 1/4 la puterea 2 va rog e urgent ​

Answer 1

Răspuns: $\bf ~\red{ \dfrac{1}{16} }$

Explicație pas cu pas:

$\bf \bigg(\dfrac{1}{4}\bigg) ^0-\bigg(\dfrac{1}{4}\bigg) ^2= 1-\dfrac{1^2}{4^2}=$

$\bf ~ \dfrac{ ^{16)}1~}{1} -\dfrac{1}{16}=\dfrac{16}{16}-\dfrac{1}{16}=\dfrac{16-15}{16}= \red{\boxed{\bf \dfrac{1}{16} }}$

$\green{\bf \underline{\star~Formule~pentru~puteri}:}$

$\bf a^{0} = 1;$

$\bf (a^{n})^{m} = a^{n \cdot m};$

$\bf a^{n}\cdot a^{m} =a^{n+m};$

$\bf a^{n}: a^{m} =a^{n-m}$
