I need help ASAP please.
with these two questions
medal is given
i need to get this test done by today or i fail please help me!!!
\[\sqrt{7}/\sqrt[4]{7}= 7^{1/2}/7^{1/4}\]
you do the same thing
i say it is answer a
first one you have correct
let me see...
did you get the answer?
i keep getting 8 3/10 but it is not negative
its whatever your heart tells you
The second one is the third choice from the top.
\[\frac{ \sqrt[5]{8}\sqrt{8} }{ \sqrt[3]{8^{5}} }\]That equals, in exponential form:
\[\frac{ 8^{\frac{ 1 }{ 5 }}8^{\frac{ 1 }{ 2 }} }{ (8^{5})^{\frac{ 1 }{ 3 }} }\]
In the numerator you have to find a common denominator and add those exponents, and in the denominator you multiply the 5 times the one-third to get 8^5/3.
The numerator becomes \[8^{\frac{ 7 }{ 10 }}\]and the denominator is\[8^{\frac{ 5 }{ 3 }}\]Because these are divided, you are required to subtract the exponent in the denominator from the exponent in the numerator.
\[8^{(\frac{ 7 }{ 10 }-\frac{ 5 }{ 3 })}\]Now you have to find a common denominator between the 10 and the 3 which is 30.
\[8^{(\frac{ 21 }{ 30 }-\frac{ 50 }{ 30 })}\]
This gives you \[8^{-\frac{ 29 }{ 30 }}\]
^ correct i see where i went wrong
