Instead of burning fossil fuels we should be concentrating on more economic uses of electricity, because electricity can be produced from any sources of energy.

Unless we do research on solar energy, wind power, tidal power, hydroelectric plants… our fossil fuels will run out and we’ll all freeze or starve to dealth. Many countries are spending much more time and money on research because the energy from the sun, the waves and the winds last forever.

Cho số A=27x58-31 Số B=27+58x26 Không tác giá tự.Hãy so sánh Số A và Số B NHANH HỘ EM :))

Cho a,b,c là các số thực khác 0, thỏa mãn: `a + b - 2017.c /c` = `b + c - 2017.a /a` = `c + a - 2017.b /b` Hãy tính giá trị của biểu thức: B= (1 + `b/a`).(1 + `a/c`).(1 + `c/b`)
