2^4x-3.5x=5^2-2^4

解答

2^{4} x - 3.5 x = 5^{2} - 2^{4}

解答

x = \frac{18}{25}

+1

十进制

x = 0.72

求解步骤

2^{4} x - 3.5 x = 5^{2} - 2^{4}

2^{4} = 16

16 x - 3.5 x = 5^{2} - 2^{4}

同类项相加:

16 x - 3.5 x = 12.5 x

12.5 x = 5^{2} - 2^{4}

5^{2} = 25

12.5 x = 25 - 2^{4}

2^{4} = 16

12.5 x = 25 - 16

数字相减:

25 - 16 = 9

12.5 x = 9

在两边乘以

10

125 x = 90

两边除以

125

x = \frac{18}{25}

solvefor x, x/2+y=0

so l v e f or x, \frac{x}{2} + y = 0

solvefor a,m-2a=1

so l v e f or a, m - 2 a = 1

0^3*0^{-1}=(0^3)/(0^1)

0^{3} \cdot 0^{- 1} = \frac{0 ^{3}}{0 ^{1}}

solvefor x,2x+5y=107

so l v e f or x, 2 x + 5 y = 107
