What is the value of this please help
Answer (2)
The symbol √ means "square root of". √16 means "square root of 16". It's a number that gives 16 when you multiply the number by itself.
There are two numbers that can both do the job. They are +4 and -4.
(+4) times (+4) = 16
(-4) times (-4) = 16
The square root of 16 is both +4 and -4, as both numbers yield 16 when multiplied by themselves. The square root symbol indicates the value that gives the original number upon being squared. Therefore, 16 = 4 and 16 = − 4 .
