Q. Simplify the expression completely.−100−4−9−−16Answer:
Question Prompt: Question prompt: Simplify the expression completely.
Simplify Square Root of 100: Simplify the square root of 100. The square root of 100 is 10, because 102=100. So, −100=−10.
Simplify Square Root of −9: Simplify the square root of −9. The square root of −9 involves an imaginary number because the square root of a negative number is not real. The square root of 9 is 3, so the square root of −9 is 3i, where i is the imaginary unit. So, −4−9=−4×3i=−12i.
Simplify Square Root of −16: Simplify the square root of −16. Similarly, the square root of −16 involves an imaginary number. The square root of 16 is 4, so the square root of −16 is 4i. So, −−16=−4i.
Combine Simplified Terms: Combine all the simplified terms.Combine −10, −12i, and −4i.The expression becomes −10−12i−4i.
Combine Imaginary Terms: Combine the imaginary terms.Combine −12i and −4i to get −16i.So, the expression now is −10−16i.
