I need help. this is the problem x^2/3+10=7x^1/3

Arlecino [84]

$\it x^{\frac{2}{3}}+10=7x^{\frac{1}{3}} \Leftrightarrow (x^{\frac{1}{3}})^2-7x^{\frac{1}
 {3}} +10=0 
\\\;\\
We\ note\ x^{\frac{1}{3}} =t \ \ and \ the \ equation \ will \ be:
\\\;\\
t^2-7t+10 = 0 \Leftrightarrow t^2 -2t-5t+10=0 \Leftrightarrow t(t-2) -5(t-2)=0$

$\it \Leftrightarrow (t-2)(t-5)=0 
\\\;\\
t-2=0 \Rightarrow t=2 \Rightarrow x^{\frac{1}{3}}=2 \Rightarrow (x^{\frac{1}{3}})^3 =2^3 \Rightarrow x = 8
\\\;\\
t-5=0 \Rightarrow t=5 \Rightarrow x^{\frac{1}{3}}= 5 \Rightarrow (x^{\frac{1}{3}})^3 = 5^3 \Rightarrow x = 125$

S = {8; 125}

Why are the solutions to the proportions 40/80 = to x/10 and x/40= 10/8 the same

Daniel [21]

Answer:

In 2 expression the value of x is different

Step-by-step explanation:

It is given that,

40/80 = to x/10 and x/40= 10/8

<u>To find the value of 40/80 = to x/10</u>

40/80 = x/10

x = (40*10)/80

x = 5

<u>To find the value of x/40= 10/8</u>

x/40 = 10/8

x = (40*10)/8

x = 50

From the given results we get the value of x is different.
