2^3x+2=48

解答

2^{3} x + 2 = 48

x = \frac{23}{4}

十进制

x = 5.75

求解步骤

2^{3} x + 2 = 48

2^{3} = 8

8 x + 2 = 48

将

2

到右边

8 x = 46

两边除以

8

x = \frac{23}{4}

a = 13000 (\frac{0.035}{1})^{12 \cdot 5}

so l v e f or x, 2 (- 4 y + x) = 4

so l v e f or a, \frac{5}{( x + 1 )} = a ∣ x - 4 ∣

(2 - 3 i) \cdot x = (2 + 3 i)

so l v e f or y, \frac{y}{2} = \frac{( z - 11 )}{- 1}
