Posted on

If you are looking for the answer of what does z equal, you’ve got the right page. We have approximately 10 FAQ regarding what does z equal. Read it below.

## ExamplesDetermine the principal roots of the following members5) 7821) ViziThink

Determine the principal roots of the following members
5) 782
1) Vizi
Think of a number when multiplied by itself results to 121
(11)(11) = 119-121 Therefore, V121 – 11
2)
Determine what number when multiplied by itself three times equals
(-3)(-3(- -)-(-5) — Therefore,
3) V625
identify what number when multiplied by itself four times will result to 625
(5)(5))(5) = 5* = 625 Therefore, V625 – 5
Pind a number when multiplied by itself is equal to 0.25
(0.5)(0.5) – (0.5) – 0.25. Therefore, 0.25 0.5
5) V2
Think of a number when multiplied by itself five times will result to 32
(2) (Z)(2)(2)(2) = 2 = 32. Therefore, V32 – 2
6) V-
In this given example, the index is 4 (which is an even number) and the radicand is -81. This
means that the root does not exist because there is no number when you multiply by itse
4 times will result to a negative number
