1)  

  What is  225 

Answer: 15


SOLUTION 1 :

Remember:

To find the square root of a given number, figure out which number squared (multiplied by itself) equals that given number.

Every positive number has both a positive and a negative square root. The radical symbol ( ) means the positive square root.

For example, 9 = 3 since 9 = 32 and 3 is positive.

Solve:

You want to find the positive square root of 225.

Figure out which number squared (multiplied by itself) equals 225.

The number 152 squared equals 225.

225 = 15 × 15 = 225

So   225   is  15.



2)  

  What is the positive square root of  5184

Answer: 72


SOLUTION 1 :

Remember:

To find the square root of a given number, figure out which number squared (multiplied by itself) equals that given number.

Every positive number has both a positive and a negative square root. The radical symbol ( ) means the positive square root.

For example, 9 = 3 *3 since 9 = 32 and 3 is positive.

Solve:

You want to find the positive square root of 5184.

Figure out which number squared (multiplied by itself) equals 5184.

The number 722 squared equals 5184.

5184 = 72 × 72 = 5184

So  the positive  5184   is  72.



3)  

  What is  49 

Answer: -7


SOLUTION 1 :

Remember:

To find the square root of a given number, figure out which number squared (multiplied by itself) equals that given number.

Every positive number has both a positive and a negative square root. The radical symbol ( ) means the positive square root.

For example, 9 = 3 since 9 = 32 and 3 is positive.

Solve:

You want to find the positive square root of 49.

Figure out which number squared (multiplied by itself) equals 49.

The number -72 squared equals 49.

49 = -7 × -7 = 49

Finally, include the negative sign to get the negative square root.

So   49   is  -7.



4)  

  What is  841 

Answer: 29


SOLUTION 1 :

Remember:

To find the square root of a given number, figure out which number squared (multiplied by itself) equals that given number.

Every positive number has both a positive and a negative square root. The radical symbol ( ) means the positive square root.

For example, 9 = 3 since 9 = 32 and 3 is positive.

Solve:

You want to find the positive square root of 841.

Figure out which number squared (multiplied by itself) equals 841.

The number 292 squared equals 841.

841 = 29 × 29 = 841

So   841   is  29.



5)  

  What is the positive square root of  3969

Answer: 63


SOLUTION 1 :

Remember:

To find the square root of a given number, figure out which number squared (multiplied by itself) equals that given number.

Every positive number has both a positive and a negative square root. The radical symbol ( ) means the positive square root.

For example, 9 = 3 *3 since 9 = 32 and 3 is positive.

Solve:

You want to find the positive square root of 3969.

Figure out which number squared (multiplied by itself) equals 3969.

The number 632 squared equals 3969.

3969 = 63 × 63 = 3969

So  the positive  3969   is  63.



6)  

  What is  1 

Answer: -1


SOLUTION 1 :

Remember:

To find the square root of a given number, figure out which number squared (multiplied by itself) equals that given number.

Every positive number has both a positive and a negative square root. The radical symbol ( ) means the positive square root.

Solve:

You want to find the positive square root of 1.

Figure out which number squared (multiplied by itself) equals 1.

The number -12 squared equals 1.

1 = -1 × -1 = 1

Finally, include the negative sign to get the negative square root.

So   1   is  -1.



7)  

  What is  196 

Answer: 14
