Here are some other examples that I got on the internet

(a)

(b)

(c)

(d)

(e)

Solution

To evaluate these we will first convert them to exponent form and then evaluate that since we already know how to do that.

(a) These are together to make a point about the importance of the index in this notation. Let’s take a look at both of these.

So, the index is important. Different indexes will give different evaluations so make sure that you don’t drop the index unless it is a 2 (and hence we’re using square roots).

(b)

(c)

(d)

(e)

As we saw in the integer exponent section this does not have a real answer and so we can’t evaluate the radical of a negative number if the index is even. Note however that we can evaluate the radical of a negative number if the index is odd as the previous part shows.

Sorry for the delay of my scribe b'coz I didn't know i was the next... So... here it is now... I hope you'll understand the first examples that i wrote there....

By the way, our great teacher asked us to answer Exercise # 26 1-7 , 9-11 , 17-20
For the next scribe,,,,, I chose.................FRANCA !!!. good luck!!!
