We know how to find the square root of any positive real number. In a similar way, we can find the square root of a negative number. The difference is that the root is not real. If the value in the radicand is negative, the root is said to be an imaginary num...
Step 1:Rewrite all square roots of negative numbers,−a, asa⋅−1whereais positive. Step 2:Fully simplify all square roots in the problem. Use the fact that−1=i. Step 3:Multiply all numbers outside of the square roots together. Multiply any numbers remaining under square r...
Square Root of a Negative Real Number (Imaginary Numbers): SMART Board Resource for Algebra 2 (Grades 6-12) (eLesson Plan)
The Square Roots of Negative Numbers:Like all other numbers, negative numbers have square roots. The numeric value of the square root of a negative number is the same numeric value as the square root of a positive number, but it will incorporate the term i at the end.Answer and Explanation...
When is square root of x^2 + y^2 equal to x+y? Explain the rules of operations involving square roots of negative numbers. Why can't polynomials have negative exponents? Why does a number raised to the zero power equal one? Derive the formula sinh^(-1) x = ln (x + sqrt(x^2 ...
A square root of x isa number r whose square is x: r2= x And we just found that: (+5)2= 25 (−5)2= 25 There aretwonumbers whose square makes 25 So both+5and−5are square roots of 25 Two Square Roots There can be apositiveandnegativesquare root!
We discovered earlier that we can square negative numbers:Example: (−3) squared (−3) × (−3) = 9And of course 3 × 3 = 9 also.So the square root of 9 could be −3 or +3Example: What are the square roots of 25? (−5) × (−5) = 25 5× 5 = 25 So the ...
