Question

me ajudem por favor​

Answer 1

Respostas:

8. p = 11

9. x = -1  

10. 12

Explicação passo-a-passo:

8.

$p=1-(-\sqrt{100} )\\\\p=1-(-10)\\\\p=1+10\\\\p=11$

9.

$x=\sqrt{81}:(4^{2} -5^{2} )\\\\x=\sqrt{81} :(16-25)\\\\x=\sqrt{81} :(-9)\\\\x=9:(-9)\\\\x=-1$

10.

$\sqrt{3600} :\sqrt{25} =60:5=12$
