Answer:
Harry needs 21 square meters of fabric for every 6 wizard cloaks he makes then Equal ratios = 21/6 = 7/2 = 14/4. Step-by-step explanation: Complete Question is : Complete the table using equivalent ratios.
Step-by-step explanation:
The pattern is:
( a - b )² = a² - 2 a b + b² ( square of last term of binomial - the missing term)
x² - 2 · 8 · x + 8² = x² - 16 x + 64 = ( x - 8 )²
The missing term is: 64
Answer:
The solution to the equation will be:
![x=\sqrt[3]{2},\:x=-\sqrt[3]{2}](https://tex.z-dn.net/?f=x%3D%5Csqrt%5B3%5D%7B2%7D%2C%5C%3Ax%3D-%5Csqrt%5B3%5D%7B2%7D)
or
, 
Step-by-step explanation:
Given the expression

simplify

Divide both sides by 9


![\mathrm{For\:}x^n=f\left(a\right)\mathrm{,\:n\:is\:even,\:the\:solutions\:are\:}x=\sqrt[n]{f\left(a\right)},\:-\sqrt[n]{f\left(a\right)}](https://tex.z-dn.net/?f=%5Cmathrm%7BFor%5C%3A%7Dx%5En%3Df%5Cleft%28a%5Cright%29%5Cmathrm%7B%2C%5C%3An%5C%3Ais%5C%3Aeven%2C%5C%3Athe%5C%3Asolutions%5C%3Aare%5C%3A%7Dx%3D%5Csqrt%5Bn%5D%7Bf%5Cleft%28a%5Cright%29%7D%2C%5C%3A-%5Csqrt%5Bn%5D%7Bf%5Cleft%28a%5Cright%29%7D)
![x=\sqrt[6]{4},\:x=-\sqrt[6]{4}](https://tex.z-dn.net/?f=x%3D%5Csqrt%5B6%5D%7B4%7D%2C%5C%3Ax%3D-%5Csqrt%5B6%5D%7B4%7D)
solving
![x=\sqrt[6]{4}](https://tex.z-dn.net/?f=x%3D%5Csqrt%5B6%5D%7B4%7D)
![=\sqrt[6]{2^2}](https://tex.z-dn.net/?f=%3D%5Csqrt%5B6%5D%7B2%5E2%7D)
Apply exponent rule: 
![=\sqrt[6]{2^2}=2^{2\cdot \frac{1}{6}}](https://tex.z-dn.net/?f=%3D%5Csqrt%5B6%5D%7B2%5E2%7D%3D2%5E%7B2%5Ccdot%20%5Cfrac%7B1%7D%7B6%7D%7D)
![=\sqrt[3]{2}](https://tex.z-dn.net/?f=%3D%5Csqrt%5B3%5D%7B2%7D)

Thus,
(or
)
similarly solving
![x=-\sqrt[6]{4}](https://tex.z-dn.net/?f=x%3D-%5Csqrt%5B6%5D%7B4%7D)
or (

Therefore, the solution to the equation will be:
![x=\sqrt[3]{2},\:x=-\sqrt[3]{2}](https://tex.z-dn.net/?f=x%3D%5Csqrt%5B3%5D%7B2%7D%2C%5C%3Ax%3D-%5Csqrt%5B3%5D%7B2%7D)
