Question

11 to 20 write down square value or cube value​

Answer 1

Answer:

The square root of 1 refers to the value which when multiplied by itself gives the result as 1. For 1, its square root can be either 1 or -1 as both 1 multiplied by 1 and -1 multiplied by -1 gives the result as 1. In general, every number has two square roots, i.e. the positive and the negative square root. In general, when talking about square roots, only the positive square root is considered (i.e. the principle square root)
