Answer:

15 and 270

Step-by-step explanation:

Using the rule of radicals

\sqrt{a} × \sqrt{a} = a

\sqrt[3]{a} × \sqrt[3]{a} × \sqrt[3]{a} = a

(a)

Given

(\sqrt{5} )² × (\sqrt{3} )²

= 5 × 3

= 15

(b)

Given

(\sqrt[3]{9} )³ × (\sqrt{30} )²

= 9 × 30

Can y’all help please
IRISSAK [1]

Answer:

x=square root 63. Basically the radical 63.

Step-by-step explanation:

So in the first triangle with the 3 in it. You have root 3 and use the a^2 +b^2=c^2 formula. So 3^2 + 3^2= x^2 and then when you solve you get radical 18^2 which is equal to radical 18 or square root 18. Then we go to the bigger triangle and we do the same formula but this time we have the c value which is 9. So we do radical 18^2 + x^2 = 9^2 and then solve that and minus 18 from the 81 since the radical goes off the 18 and you get square root63.

Sorry i couldn't use the signs. Sorry If I'm wrong Hope this helps!.
