Question

Please solve this answer

Answer 1

2 + root x = 9

root x = 7

=> x = 49

So, answer is 49

Answer 2

Answer:

1) x=49

2) 5

Step-by-step explanation:

1) $\sqrt{2+\sqrt{x} } =3$

2+$\sqrt{x}$=9

$\sqrt{x} =7$

x=49

2)$\sqrt{7230} = 85.03$

This means the next lowest whole number from 85.03 will be the next lowest whole number which can be squared.

Therefore 85^2= the next lowest square number= 7225.

to go from 7230 to 7225 you must subtract 5 so the answer is 5.

Hope this helps.
