Answer:
x = -12/5
Step-by-step explanation:
hope this helps you
Answer:
yes for the first one
because if you take number one for an example and use it for y
1^7*1^7*1^7=1 and 1^7*7*7=1
they both equal one
2.) 
![\sqrt[3]{x}\sqrt[6]{x}=\:x^{\frac{1}{3}}x^{\frac{1}{6}}=\:x^{\frac{1}{3}+\frac{1}{6}}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%7D%5Csqrt%5B6%5D%7Bx%7D%3D%5C%3Ax%5E%7B%5Cfrac%7B1%7D%7B3%7D%7Dx%5E%7B%5Cfrac%7B1%7D%7B6%7D%7D%3D%5C%3Ax%5E%7B%5Cfrac%7B1%7D%7B3%7D%2B%5Cfrac%7B1%7D%7B6%7D%7D)

join 1/3+1/6= 1/2
then you get the answer

Question 5:

Answer:
x ≥ 661.424°F or x[661.424,∞) and x ≤ - 27°F or x(-∞,-27]
Step-by-step explanation:
The melting point of the substance is - 32.78°C, then the melting point in °F is given by
⇒
⇒
⇒ F = - 27.004°F
Again, the boiling point of the substance is 349.68°C, hence, the boiling point in °F is
⇒ F = 661.424°F
Therefore, the range of temperature in °F for which the substance will not be in liquid state will be x ≥ 661.424°F or x[661.424,∞) and x ≤ - 27.004°F or x(-∞,-27.004], where x is the temperature of the substance in °F. (Answer)
