Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
4*(-2*x+7)-(24)=0
Step by step solution :
Step 1 :
Equation at the end of step 1 :
4 • (7 - 2x) - 24 = 0
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
4 - 8x = -4 • (2x - 1)
Equation at the end of step 3 :
-4 • (2x - 1) = 0
Step 4 :
Equations which are never true :
4.1 Solve : -4 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
4.2 Solve : 2x-1 = 0
Add 1 to both sides of the equation :
2x = 1
Divide both sides of the equation by 2:
x = 1/2

After solving ![\sqrt[5]{128x^8y^2}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B128x%5E8y%5E2%7D)
we get ![2x\sqrt[5]{4}\sqrt[5]{x^3}\sqrt[5]{y^2}](https://tex.z-dn.net/?f=2x%5Csqrt%5B5%5D%7B4%7D%5Csqrt%5B5%5D%7Bx%5E3%7D%5Csqrt%5B5%5D%7By%5E2%7D)
Step-by-step explanation:
We need to solve
Applying the rule: ![\sqrt[a]{xy}=\sqrt[a]{x}.\sqrt[a]{y}](https://tex.z-dn.net/?f=%5Csqrt%5Ba%5D%7Bxy%7D%3D%5Csqrt%5Ba%5D%7Bx%7D.%5Csqrt%5Ba%5D%7By%7D)
![\sqrt[5]{128x^8y^2}\\=\sqrt[5]{128}\sqrt[5]{x^8}\sqrt[5]{y^2}\\We\,\,know\,\,that\,\,128=2\times2\times2\times2\times2\times2\times2=2^7\,\,or\,\,2^5.2^2\\=\sqrt[5]{2^5.2^2}\sqrt[5]{x^5.x^3}\sqrt[5]{y^2}\\=(2^5)^{\frac{1}{5}}\sqrt[5]{2^2}\sqrt[5]{x^5}\sqrt[5]{x^3}\sqrt[5]{y^2}\\=2x\sqrt[5]{4}\sqrt[5]{x^3}\sqrt[5]{y^2}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B128x%5E8y%5E2%7D%5C%5C%3D%5Csqrt%5B5%5D%7B128%7D%5Csqrt%5B5%5D%7Bx%5E8%7D%5Csqrt%5B5%5D%7By%5E2%7D%5C%5CWe%5C%2C%5C%2Cknow%5C%2C%5C%2Cthat%5C%2C%5C%2C128%3D2%5Ctimes2%5Ctimes2%5Ctimes2%5Ctimes2%5Ctimes2%5Ctimes2%3D2%5E7%5C%2C%5C%2Cor%5C%2C%5C%2C2%5E5.2%5E2%5C%5C%3D%5Csqrt%5B5%5D%7B2%5E5.2%5E2%7D%5Csqrt%5B5%5D%7Bx%5E5.x%5E3%7D%5Csqrt%5B5%5D%7By%5E2%7D%5C%5C%3D%282%5E5%29%5E%7B%5Cfrac%7B1%7D%7B5%7D%7D%5Csqrt%5B5%5D%7B2%5E2%7D%5Csqrt%5B5%5D%7Bx%5E5%7D%5Csqrt%5B5%5D%7Bx%5E3%7D%5Csqrt%5B5%5D%7By%5E2%7D%5C%5C%3D2x%5Csqrt%5B5%5D%7B4%7D%5Csqrt%5B5%5D%7Bx%5E3%7D%5Csqrt%5B5%5D%7By%5E2%7D)
