Question 338554
1. Find the root if it is a real number:
Square Root -561
Is this defined as NOT A REAL NUMBER?
-561 is a real number
{{{sqrt(-561) = sqrt(-1)*sqrt(561)}}}
= {{{isqrt(561)}}} All you can do.
----------------------
2. Find the root if it is a real number:
Index is 4 and negative sign is outside the root
With 81 as the square root inside
Is this defined as -3?
81 is a real number, and it have 4 4th roots.
{{{sqrt(sqrt(81))}}} = ± {{{sqrt(9)}}} and ± {{{sqrt(-9)}}}
= ± 3 and ± 3i
--------------
3. Simplify the root.
Negative on the outside, square root x^28
Is this defined as -x^14?
or is it defined as |-x^14|?
Just -x^14
-------------
4. Simplify the first converting to rational exponents. Assume that all variables represent positive real numbers.
Square Root z^28
Is this defined as z^14?
It is.
----------
I'm confuse on whether it will be an absolute value with | | or divide them by 2? No absolute values involved.
