• Square Root Of 45

• square root 45

  45 = 9*5

  45 = 3 sqrt(5)

• answer if b

  45 = 9 x 5 and the square root of 9 is 3, which leaves 5 under the radical sign.

• the answer is 3 square root 5. 15 and three go into 45. 3 and 5 go into 15. two threes mean a three is outside the square root sign. the 5 is left inside.

• Root 45=Root9 x Root5

  So Root9 is 3….

  so its 3Root5

  b

• b. 3 root 5

• b) 3 Squat root 5

• You can separate it into sqrt(9X5). Since you can take the 9 out, the answer would be 3 sqrt 5. The correct answer would be B.
