7.
((1/5 * 1/3)raise to the power -1 divide by 1/6)
((3+5/15)raise to the power -1divided by 1/6)
((8/15) raise to the power -1 divide by 1/6)
15/8 divide by 1/6
8/15 * 1/6
=8/90

8.
1.2 raise to the power is 1
therefore,
(1+1/3)*3*3
4/3*9
4*3
=12

2.
(1/2*1/3)divided by 1/2 raise to the power 3
1/6*1/8
1/24

3.
2 raise to  the power 2+3 raise to the power 2+4 raise to the power 2
4+9+16
13+16
=29


4.
3.((3/2)raise to the power -2)raise to 2
((2/3)raise to 2 )raise to 2
(4/9)raise to 2
=16/81

2.((1/9)raise to -2)raise to -1
(9)raise to 2)raise to -1
(81)raise to -1
=1/81

1.
(4/9) raise to -2
9/4 raise to 2
=81/16


hope this helps you...
