Answer:

5<em>i</em>

Step-by-step explanation:

  1. = \sqrt{-1 * 25}
  2. = \sqrt{-1}\sqrt{25}
  3. = \sqrt{-1} * 5

Rule: \sqrt{-1} = <em>i</em>

So you get <em>i  </em>* 5<em> </em>=<em> </em>5<em>i</em>

Is the least number to be added to 5607 to get a perfect square. <br> pls add the steps.
daser333 [38]

Answer:

18

Step-by-step explanation:

70^2 = 4900 < 5607 < 6400 = 80^2

so sqrt(5607) is a two-digit number with tenth-digit 7

71^2 = 5041, 72^2 = 5184, 73^2 = 5329, 74^2 = 5476, 75^2 = 5625

so the smallest square bigger than 5607 is 75^2, which is 5625

so the number should ne 5625 - 5607 = 18
