Question

用matlab求解如下方程组，多谢！！！

a+b*sqrt(4.43+19.6249*c)=8.7271

a+b*sqrt(6.13+37.5769*c)=7.7851
a+b*sqrt(2.23+4.9729*c)=5.0398

Answer 1

语句：[a b c]= solve('a+b*sqrt(4.43+19.6249*c)=8.7271','a+b*sqrt(6.13+37.5769*c)=7.7851','a+b*sqrt(2.23+4.9729*c)=5.0398','a','b','c')
结果：a =
-15.597455144468663247636605335783
b =
15.785747556730826448662849692202
c =
-.10474291635508139109869813039686

追问

c是-0.10474291635508139109869813039686吗

追答

对，小数点前的0自动省略了
