Not Sure On How To Type This Out But Can Anyone Help Me class=

Sagot :

Answer:

484

Step-by-step explanation:

This is because 22 squared is 484.

When you take something out from under the square root symbol, you have to square it.

Thus, a number outside the square root to the left of the symbol was originally that same number squared under the square root symbol.

Thus as 22 is outside the symbol, it was originally 22 squared while under the symbol, and 22 squared is 484.

Answer:

484, because 22 squared is equivalent to 484z
