Answer:
5.-26
6. 27
7. 133
8.16/15625
9.16
10.8004
Step-by-step 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
