I understand the first step: (2^4 x 7^2)^2/3 however i do not understand how you get to the next stage which is:

(24×72)2/3=22×4/3×72×2/3=22×22/3×7×71/3,

28×281/3

Please can someone help me understand the last 2 steps. I have tried looking this up but cannot find an explanation of how to multiple an exponent with another exponent which is a fraction.

Thanks

Thanks

The square roots of 100 are + or -10, yes? So why when one simplifies surds are we able to ignore negative roots?

e.g. ⎷300 -⎷48 =⎷100x3 -⎷16x3 = 10⎷3 - 4⎷3 = 6⎷3

what about the negative root of 100, and the negative root of 16?

Thanks in advance for your help. ]]>

If the input is odd, just return that number i.e f(2n+1) = 2n+1

If the input is even return the odd number one less than it i.e f(2n) = 2n-1

So for example f(4)=3, f(3)=3 ]]>

As I know sqrt * 4 x sqrt * 4 = 4 because sqrt * 4 = 2, so 2 x 2 = 4 but what's about sqrt * 1? ]]>
