Question

whats is the square root of -1 as well as tell me about what happens if a number has exponent left instead of right like this ²2 or in the down left​

Answer 1

The square root of -1 is 'i' and exponent placement indicates the power or the number of times the base is multiplied by itself.

Step-by-step explanation:

An imaginary unit called 'i' is the square root of -1 . It is represented by the symbol 'i' and is defined as the number that when squared gives -1.

In other words, i² = -1. It is widely used in complex numbers and has various applications in mathematics and science.

As for the exponent placement, if a number has an exponent written as a superscript or subscript, it indicates the power or the number of times the base is multiplied by itself.

For example, ²2 means 2 squared, which is equivalent to 2 multiplied by itself, resulting in 4. On the other hand, the down left placement can represent inverse functions or reciprocals.

For instance, x⁻² represents the reciprocal of x squared, which is 1 divided by x².
