Answer:

(a) (9/-5) ^2×(5/-3) ^3×(5/3) ^6

when we reciprocal it. So, digit come in

addition.

(81/25) ×(125/-9) ×(15, 625/729)

81/25×125/-9×15, 625/729

158,203,125/-6, 536 //ans

(b) [(-7/9×-9/7)^-3 ]÷(-7/9) ^-3

[(63/63) ^-3]÷(-7/9) ^-3

(63/63×-7/9) ^-3

(-441/567) ^-3

(567/-441) ^3

182,284,263/388, 962//ans

(c) (2/-3) ^4×(-3/2)

(16/81) ×(-3/2)

16/81×-3/2

-48/162// ans

(d) (-3/7) ^2×-3

(-3/7) ^-6

(7/-3) ^6

117,649/729

(e)[ (5×2) ^-2]×10^2

(10^-2) ×10^2

(1/10) ^2×10^2

(1/10×10) ^2

(1) ^2

1// ans

(f) [(-1/3)^ -4-(-2) ]^3

[(-1/3) ^-2]^3

(-1/3) ^-2×-3

(-1/3) ^-5

(3/-1) ^5
