2^(2m-1)×16×8^(m-1)+(-4^m)×8^mRT,2^(2m-1)×16×8^(m-1)+(-4^m)×8^m
当m=1/2时,求15m²-9-{-4m²+[5m-8m²-(2m²-m)+9m²]-3m}
已知2^m=a,化简16×2^2m-1 ×2^3m-1 -4^m ×8^m
已知2^m=a,化简16×2^2m-1 ×2^3m-1 -4^m ×8^m
4m(m的平方-2m-1)+m(2m+5)(5-2m)
m*m-2m等于1,则2m*m-4m+2012
化简求值 m-4/m^2-9(1加上 14m-7/m^2+8m+16)÷1/m-3 其中m=5化简求值：（m-4）/（m^2-9）•{1+[（14m-7）/（m^2+8m+16)]}÷[1/（m-3） ]其中m=5
