Help me plssssssssssssssssssssss :)

Answer 1

Answer:

19.$-\frac{5}{6}^{3}$

20.$s^{2} *7^{3}$

21.$4^{2} * b^{4}$

22. 97.2

23. 234

Step-by-step explanation:

$k^{4}*m\\ 3^{4} *\frac{5}{6}\\ 81*\frac{5}{6}=97.2$

$(c^{3}+ d^{4})^{2} -(c+d)^3\\(-1^3+2^4)^2-(-1^3+2^3)\\-1+256+1+8\\=234$

I hope this helps.
