Explain as well.

1. (8x)^3*8^-4

2. 2x^-5*y^-3

3. (4x^4y^-3)^-2

4. 1/(3x)^-2

**Bosnian**, Friday, February 3, 2012 at 4:49am( 8 x ) ^ 3 * 8 ^ ( -4 ) =

8 ^ 3 * x ^ 3 / 8 ^ 4 =

8 ^ 3 * x ^ 3 / ( 8 ^ 3 * 8 ) =

[ ( 8 ^ 3 ) / ( 8 ^ 3 ) ] * ( x ^ 3 / 8 ) =

x ^ 3 / 8

2 x ^ ( - 5 ) * y ^ ( - 3 ) =

2 / ( x ^ 5 * y ^ 3 )

[ (4 x ^ 4 y ^ ( - 3) ] ^ ( - 2 ) =

[ ( 4 x ^ 4 / y ^ 3 ) ] ^ ( - 2 ) =

1 / ( 4 x ^ 4 / y ^ 3 ) ^ 2 =

1 / ( 16 x ^ 8 / y ^ 6 ) =

y ^ 6 / ( 16 x ^ 8 )

1 / ( 3 x )^ ( - 2 ) =

1 / [ 1 / ( 3 x ) ^ 2 ] =

1 / [ 1 / ( 9 x ^ 2 ) ] =

9 x ^ 2 / 1 =

9 x ^ 2
