5.-26

6. 27

7. 133

8.16/15625

9.16

10.8004

Explanation:

5.(20/5)³ - 10(3)²

=>4³ - 10.9

=>64-90

=>-26

6.{(27-12)/(8-3)}³

=>(15/5)³

=>3³

=>27

given that s=2 ; t=5 (for 7&8)

7. s³ + t³

=>2³ + 5³

=>133

8.{(s+2)/ 5t²}²

=>{(2+2)/5.5²}²

=>(4/125)²

=>16/15625

9.-4d²+15d²+5 ; d=1

=>-4.(1)²+15.(1)²+5

=>-4+15+5

=>16

10.

Given that,

(5x²)³+16y/4y ;x=2,y=3

=>125x⁶+16y/4y

=>125.(2)⁶+4

=>8004
