Answer 1

Answer:

a.-3125/32

b.1/27

c.s^3/2 × t^-3

Step-by-step explanation:

a.(-2.5)^3/(-2.5)^-2

=(-2.5)^3-(-2)

=(-2.5)^5

= -3125/32 OR -97.65

b.(3)^3.(3)^-6

=3^3+(-6)

=3^-3

=1/3^3

=1/27

c.S^2. t^-1/(s^4t^4)^1/2

=S^2.t^-1/(s^4×1/2).(t^4×1/2)

=S^2. t^-1/s^1/2.t^2

=s^2-1/2.t^-1-2

=s^2/3.t^-3
