7 (or -7)
(Since 7 x 7 = 49, -7 x -7 = 49)
It is: 7

The square root of a number is the numeral that makes that number when multiplied by itself- for example, 7 is the square root of 49, because 7 x 7 = 49; 5 is the square root of 25, because 5 x 5 = 25, and so on.
It is the number that is multiplied by itself to get another number.For example, what number do you multiply by itself to get 25?The answer is 5, because 5 multiplied by itself is 25.Another way to say 5 x 5 is 'five squared', written as 5225 (i.e. the result of 5 x 5) is 'the square' of 5.And 5 is the root, the 'square root' of 25.What might be the square root of 9? (3, because 3 x 3 = 9)So what is the square root of 49 ?
7 multiplied by 7 is 49.

An exponent is used to indicate that a number is multiplied by itself a specified number of times. For example, to multiply 4 by itself 9 times, you would write 49.
If by w2 you mean "w squared", then it cannot be done. BECAUSE w2 + 49 = 0 w2 +49 - 49 = 0 - 49 w2 = -49 w2 means a number multiplied by itself. Any number multplied by itself will result in a POSITIVE number. positive x positive = positive negative x negative = negatve
The number is 7: 74=7*7*7*7=49*49=2401. 7
