(-2)^2-sqrt{9}+(sqrt{2}-1)^0+(1/3) eching

$$( - 2 ) ^ { 2 } - \sqrt { 9 } + ( \sqrt { 2 } - 1 ) ^ { 0 } + ( \frac { 1 } { 3 } )$$

Baholash

$$\frac{7}{3}\approx 2,333333333$$

Yechim qadamlari

2 daraja ko‘rsatkichini -2 ga hisoblang va 4 ni qiymatni oling.

$$4-\sqrt{9}+\left(\sqrt{2}-1\right)^{0}+\frac{1}{3}$$

9 ning kvadrat ildizini hisoblab, 3 natijaga ega bo‘ling.

$$4-3+\left(\sqrt{2}-1\right)^{0}+\frac{1}{3}$$

1 olish uchun 4 dan 3 ni ayirish.

$$1+\left(\sqrt{2}-1\right)^{0}+\frac{1}{3}$$

0 daraja ko‘rsatkichini \sqrt{2}-1 ga hisoblang va 1 ni qiymatni oling.

$$1+1+\frac{1}{3}$$

2 olish uchun 1 va 1'ni qo'shing.

$$2+\frac{1}{3}$$

\frac{7}{3} olish uchun 2 va \frac{1}{3}'ni qo'shing.

$$\frac{7}{3}$$

Omil

$$\frac{7}{3} = 2\frac{1}{3} = 2,3333333333333335$$
