根号三分之二乘根号六又四分之三除以根号一又八分之一
=√(2/3)X√(6+3/4)÷√(1+1/8)
=√(2/3)X√(27/4)÷√(9/8)
=√(2/3)X√(27/4)X√(8/9)
=√(2X27X8)/(3X4X9)
=√4
=2
(2/3)^0.5×(6又3/4)^0.5÷(1又1/8)^0.5
=[(2/3)×(6又3/4)÷(1又1/8)]^0.5
=[2/3×27/4×8/9]^0.5
=1
√(2/3)×√(6+3/4)÷√(1+1/8)
=√6/3×3√3/2×2√2/3
=2
√2/3*√27/4÷√9/8
=√6/3*(3√3/2)*(2√2/3)
=2
∵2/3×27/4÷9/8
=2/3×27/4×8/9
=4
根号4=2
