Rewrite the expression using rational exponent notation. rad 7

OpenStudy (anonymous):

Okay, so the way rational exponent notation works, is that you are essentially changing a square root [or combination of root and powers] into a fractional exponent: square root is an exponent of 1/2, cube root is 1/3, fourth root is 1/4, etc., and of course your powers as exponents, 1, 2, e, etc. Basically, you multiply the power and root exponents, so for this one, it's as simple as 7^(1/2). But let's say you have sqrt(7^5) [or you would probably type it as rad(7^5)]? Just multiply! 5*(1/2), so you end up with 7^(5/2)! Another way to look at it is, the index of the root is in the denominator, while your exponent [power] is in the numerator. Hope this helps!

I don't even know what "rad 7" means to begin with

OpenStudy (ammarah):

so for rad 7 its 7^(1/2) this is simply the answser?

OpenStudy (the_fizicx99):

What does "rad 7" mean?

OpenStudy (ammarah):

How about for this one:|dw:1385587326844:dw|

OpenStudy (ammarah):

it means radical 7

OpenStudy (anonymous):

Yes, rad7 = 7^(1/2)

OpenStudy (anonymous):

do the same thing with your 3*rad(2): You will have 3 multiplied by rad(2) [think of these as separate things]. What you want to do is the same thing as you did with 7, but multiply it by 3. Does that make sense? So what would the answer be?
