√5:(x^2) in exponential form

Question

√5:(x^2)  in exponential form

turingtest · Answer

is this the problem?$$\sqrt{5x^2}$$

anonymous · Answer

no

turingtest · Answer

can you try to type it with the equation feature then?

anonymous · Answer

^5√x^2

turingtest · Answer

oh you mean$$\sqrt[5]{x^2}$$right?

anonymous · Answer

yes ;)

turingtest · Answer

The rule in general is$$\sqrt[b]{x^a}=x^{a/b}$$so in your case
a=2
b=5
which gives us$$\sqrt[5]{x^2}=x^{2/5}$$

turingtest · Answer

To type these in the future write it like this:

sqrt[5]{x^2}

Then highlight it and click on the "equation" feature (in the lower left). You should get used to using it so we can read your problems correctly.

49(-1/2) Simplify

turingtest · Answer

there is not much to be done here because 49 is not divisible by 2, so just multiply across:$$49*{-1\over2}={49\over1}*{-1\over2}=?$$you should be able to do that yourself.

49(-1/2) Simplify 

A. -7
B.  7
C,  -1/7
D. 1/7

turingtest · Answer

oh you wanted $$49^{-1/2}=\sqrt{49^{-1}}=\sqrt{1\over49}={1\over \sqrt{49}}=\pm{1\over7}$$so both C and D are correct

turingtest · Answer

please use ^ symbol for exponents:
49^(-1/2)
is how your problem should be written.
