solvefor x,(x-14)^2*10^{-15}=3

解答

求解

x, (x - 14)^{2} \cdot 1 0^{- 15} = 3

解答

x = 1000000030 + 14, x = - 1000000030 + 14

+1

十进制

x = 54772269.75051 \dots, x = - 54772241.75051 \dots

求解步骤

(x - 14)^{2} \cdot 1 0^{- 15} = 3

化简

1 0^{- 15} : \frac{1}{1 0 ^{15}}

(x - 14)^{2} \frac{1}{1 0 ^{15}} = 3

在两边乘以

1 0^{15}

(x - 14)^{2} = 3 \cdot 1 0^{15}

对于

(g (x))^{2} = f (a)

解为

g (x) = f (a), - f (a)

解

x - 14 = 3 \cdot 1 0^{15} : x = 1000000030 + 14

解

x - 14 = - 3 \cdot 1 0^{15} : x = - 1000000030 + 14

二次方程组的解是:

x = 1000000030 + 14, x = - 1000000030 + 14
