Question

помогите пожалуйста​

Answer 1

Ответ:

$\displaystyle \Big(\frac{1}{2}\Big)^{-2}-\Big(\frac{3}{5}\Big)^0+\Big(\frac{1}{3}\Big)^2:3=2^2-1+\frac{1}{9}:3=4-1+\frac{1}{27}=3+\frac{1}{27}=\frac{82}{27}$

Answer 2

Ответ:

$3 \frac{1}{27} .$

Объяснение:

$( \frac{1}{2} ) {}^{ - 2} - ( \frac{3}{5} ) {}^{0} + ( \frac{1}{3} ) {}^{2} \div 3 = 2 {}^{2} - 1 + \frac{1}{9} \times \frac{1}{3} = 4 - 1 + \frac{1}{27} = 3 + \frac{1}{27} = \frac{81 + 1}{27} = \frac{82}{27} = 3 \frac{1}{27} .$
