已知根号2.36=1.536,根号23.6=4,.858.(1)求根号236和根号0.00236的值; (2)若根号x=0.4858,求x的值
已知根号2.36=1.536,根号23.6=4,.858.(1)求根号236和根号0.00236的值; (2)若根号x=0.4858,求x的值
已知根号2.36=1.536,根号23.6=4,.858.(1)求根号236和根号0.00236的值; (2)若根号x=0.4858,求x的值
根号236=15.36,根号0.00236=0.04858.
X=0.236
(1)√236=√100×2.36=10√2.36=15.36
√0.00236=√0.0001×23.6=0.01√23.6=0.04858
(2)√x=0.4858=0.1×4.858=0.1√23.6
∴√x=√0.236
x=0.236

1.根号236=15.36 根号0.002360=0.04858
2.x=0.236
已知根号2.36=1.536,根号23.6=4.858,若根号x=0.485则X=?
1.已知根号2.36=1.536,根号23.6=4.858求根号236和根号0.00236的值若根号x=0.4858,求x的值若根号a*10的6次方=1536,求a的值
已知:根号x=根号a+[1/(根号a)] ,(0
已知根号2009=根号x+根号y,且0
已知a=(根号5-根号3)/(根号5+根号3) b=(根号5+根号3)/(根号5-根号3) 求根号(a3+b3-367)
1.已知根号2.36=1.536,根号23.6=4.858 求根号236和根号0.00236的值 若根号x=0.4858,求x的值 (要具体过程
已知根号2.36=1.536,根号23.6=4,.858.(1)求根号236和根号0.00236的值; (2)若根号x=0.4858,求x的值
已知根号x+根号y=根号5,根号xy=根号15-根号3,求x+y的值
已知x=2y,化简根号y/(根号x-根号y)-根号y/(根号x+根号y)
已知x=2y,化简根号y/(根号x-根号y)-根号y/(根号x+根号y)
已知x=2y,化简:根号y/根号x -根号y -根号y/根号x +根号y
已知x =2y 化简(根号y/根号x -根号y )-(根号y/根号x +根号y)
已知x=(根号8)-( 根号7)/(根号8)+(根号7),y=(根号8)+(根号7)/(根号8)-(根号7).已知x=(根号8)-( 根号7)/(根号8)+(根号7),y=(根号8)+(根号7)/(根号8)-(根号7).求x+y+2(根号xy)/(根号x)+(根号y)
已知:根号2.36=1.536,根号23.6=4.858,若对于实数a有根号a=0.4858,则a=( )可以说明理由吗?
代数式求值.已知x=2,y=根号3,求 (根号x-根号y)/(根号x+根号y)+(根号x+根号y)/(根号x-根号y)已知x=2,y=根号3,求 (根号x-根号y)/(根号x+根号y)+(根号x+根号y)/(根号x-根号y)
已知根号x=根号2-1/根号2,根号y=根号3-1/根号3,求代数式【(x+y)/(根号x-根号y)】-求代数式【(x+y)/(根号x-根号y)】-2xy/(x根号y-y根号x)已知根号x=根号2-(1/根号2),根号y=根号3-(1/根号3),求代数
已知根号2=a,根号10=b,则根号12.5=?,根号0.016=?
已知a=根号99-根号98,b=根号98-根号97
