Answer 1

3978:\(\left[359-\left(2^7:2^4+39.8\right)\right]\)

3978:\(\left[359-\left(2^3+312\right)\right]\)

3978:\(\left[359-320\right]\)

3978:39=102

 

Answer 2

5²+\(\left[250-150:\left(35.2^2-90\right)\right]\)

25+\(\left[250-150:\left(35.4-90\right)\right]\)

25+\(\left[250-150:50\right]\)

25+2=27
