三分之二倍乘根号三是否等于三分之二倍的根号三
2/3*√(3√3)
=2/3*(3√3)^(1/2)
=2/3*(3*3^(1/2))^(1/2)
=2/3*(3^(1+1/2))^(1/2)
=2/3*(3^(3/2))^(1/2)
=2/3*3^(3/2*1/2)
=2/3*3^(3/4)
=2*3^(3/4-1)
=2*3^(-1/4)
=2除以4次根号3
2/3*√(3√3)
=2/3*(3√3)^(1/2)
=2/3*(3*3^(1/2))^(1/2)
=2/3*(3^(1+1/2))^(1/2)
=2/3*(3^(3/2))^(1/2)
=2/3*3^(3/2*1/2)
=2/3*3^(3/4)
=2*3^(3/4-1)
=2*3^(-1/4)
=2除以4次根号3
