2^n+2=2 eching

$$2 ^ { n + 2 } = 2$$

n uchun yechish

$$n=-1$$

Logaritm ifodasidan foydalanish qadamlari

Tenglamani yechish uchun eksponent va logaritmlarning qoidalaridan foydalanish.

$$2^{n+2}=2$$

Tenglamaning ikkala tarafiga tegishli logaritmni chiqarish.

$$\log(2^{n+2})=\log(2)$$

Darajaga ko'tarigan logaritm raqami raqam logaritmining darajasidir.

$$\left(n+2\right)\log(2)=\log(2)$$

Ikki tarafini \log(2) ga bo‘ling.

$$n+2=\frac{\log(2)}{\log(2)}$$

Asosiy tenglamani almashtirish orqali \frac{\log(a)}{\log(b)}=\log_{b}\left(a\right).

$$n+2=\log_{2}\left(2\right)$$

Tenglamaning ikkala tarafidan 2 ni ayirish.

$$n=1-2$$
