Full solution

Q. Simplify the expression completely.\newline249+64+36 2 \sqrt{49}+\sqrt{-64}+\sqrt{-36} \newlineAnswer:
  1. Positive Number Simplification: Simplify the square root of a positive number.\newlineWe have 2492\sqrt{49}, which is 22 times the square root of 4949. The square root of 4949 is 77.\newlineSo, 249=2×7=142\sqrt{49} = 2 \times 7 = 14.
  2. Negative Number Simplification: Simplify the square root of a negative number.\newlineWe have 64\sqrt{-64}, which involves the square root of a negative number. The square root of a negative number is an imaginary number. We can write 64\sqrt{-64} as 64×1\sqrt{64} \times \sqrt{-1}, which is 8i8i, where ii is the imaginary unit.
  3. Another Negative Number Simplification: Simplify another square root of a negative number. Similarly, 36\sqrt{-36} can be written as 36×1\sqrt{36} \times \sqrt{-1}, which is 6i6i.
  4. Combining Results: Combine the results from the previous steps.\newlineNow we combine the results from steps 11, 22, and 33.\newline1414 (from step 11) + 8i8i (from step 22) + 6i6i (from step 33) = 14+(8i+6i)=14+14i14 + (8i + 6i) = 14 + 14i.
