The correct expression is,
⇒ 14i
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
Expression is,
⇒ √- 25 + 2√- 9
Hence, We can change it into monomial in term of i as;
⇒ √- 25 + 2√- 9
⇒ √- 5² + 2 √- 3²
⇒ 5i + 3 × 3i
⇒ 5i + 9i
⇒ 14i
Since, i² = - 1
Thus, The correct expression is,
⇒ 14i
