Subtract 823−−√−23−−√ . (1 point)
To solve this, we can first calculate the square root of -23. However, the square root of a negative number is not a real number. Thus, the expression is undefined.
To subtract 823 - √23 - √23, let's break it down step-by-step:
Step 1: Start by subtracting the two square root terms.
- √23 - √23 = 0
Step 2: Now subtract 823 from 0.
823 - 0 = 823
Therefore, the result of subtracting 823 - √23 - √23 is 823.
To subtract 823−−√−23−−√, we need to simplify the square roots first.
√23 = 4.79583152331 (approximated to five decimal places)
√−23 is not a real number because square roots of negative numbers are considered imaginary.
Therefore, we cannot subtract these square roots since one of the terms is not a real number.
