What is the sum of StartRoot negative 2 EndRoot and StartRoot negative 18 EndRoot?

4 StartRoot 2 EndRoot

4 StartRoot 2 EndRoot i

5 StartRoot 2 EndRoot

5 StartRoot 2 EndRoot i

B. 4 StartRoot 2 EndRoot i

Step-by-step explanation:

Given the surd function √-2 and √-18, we are to fund the sum of both values.

Taking the sum:

= √-2 + √-18

= (√2 * √-1) + (√18 * √-1)

from complex numbers, √-1) = i

The expression becomes

= √2 i + √18 i

= √2 i + √9*2 i

= √2 i + 3√2 i

= 4 √2 i

= √-2 + √-18 = 4 √2 i

The result is 4 StartRoot 2 EndRoot i
