Answer:
Below in bold.
Step-by-step explanation:
c) 3 x (9^2)^3/4 x ((81^3)^5/6
= 3 x 81^3/4 x 81^15/6
= 3 x 81^(3/4 + 15/6)
= 3 x 81^13/4
= 3 x 3^13
= 3^14
= 4,782,969.
f) (5x^-1y^2)^-2 / (25 x^2 y - 1)^2
= 5^-2 x^2y^-4 / 625 x^4y^-2
= 5^-2 x^-2 y^-2 / 5^4
= 5^-6 x^-2y^-2
= 0.000064x^-2y^-2.
Answer:
21cm
Step-by-step explanation:
<em>Solution,</em>
<em>Length of fish=40mm=40/10=4cm</em>
<em>Length of pig=25cm</em>
<em>Now, </em>
<em>Difference of their length=25cm-4cm=21cm</em>
<em />
<em>Hence,the pig is 21cm long than the fish</em>
