1/2 power is square root
-1 is inverse

therefore 4/9 is inversed and square rooted which is 3/2.

what is right?

In case you didn't notice both answers give the same answer.

BTW, I think you need to work on your grammar too.

Think of it like multiple operations

1. A single whole 3 as the exponent, such as in 4^3 means raise the base to that power, which in this case is 4*4*4 = 64

2. A single fraction such as 4^(1/2) basically does the inverse of squaring the base, in that it takes that root, which in this case is the 2nd root, or the 'square' root, or sqrt(4)= 2

***Remember that a fraction consists of an integer divided by an integer. This applies especially to situations were you have non-single fractions***

-A non-single fraction exponent such as 4^(3/2) combines both rules 1 and 2. In this case the numerator is what the base will be raised to, and the denominator is what root will be taken. In this case, rase the base, 4, to the third power, equalling 64, and take the square root of that, which equals 8, since 8*8 = 64

If you still do not understand it you're a freakin' dumbass*

Thanks I didn't feel like typing all that out.

Unfortunately for you Goosemaster can?t take your tests and by the looks of things you don?t stand a chance on your own.

The best advice anyone could have given you was look it up an figure it out on your own.

Who the hell are you to insult someone's math level? This person is actively seeking out help, which is a lot better than being a snotty prick with a keyboard and internet access.

You guys are so cool....making fun of me over the internet because I forgot how to do something from algebra 2...You must all have really high self-esteem.

Altough Mr. Cherrybomb her was rather harsh, he does have a valid point.

The best way to study and effectively learn math is to struggle with it.
