Please help, medal and fan
Assuming x in nonnegative, \(\sqrt{x^2} = x\)
\(x^6 = x^2 \times x^2 \times x^2\)
true, so \[x ^{6} = x ^{3} ?\]
I think you meant \(\sqrt{x^6} = x^3\) which is correct.
yeah, thats what i meant. but then we have that 24 attached?
That takes care of the x part. Now we need to take care of the number part.
Can you factor 24 into a product of two numbers, one of which being a perfect square?
since 4 is a perfect square we could split it up into \[\sqrt{4 * 6}\]
and then, keep simplifying and we get \[2\sqrt{6}\] , right?
Exactly. Now split the root into a product of roots, and take the root of 4. \(\sqrt{24} = \sqrt{4 \times6} = \sqrt 4 \sqrt6\)
Correct.
so its c?
Now put it all together, the x part and the number part.
Correct.
Thanks for your help! :D
You're welcome.
The general idea here is to split up the radicand into a product of squares and what's left over. Then every square can have its square root taken. What is left stays inside the root.
ok, i understand. :D
Great. You're welcome.
