b

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.

looks simple to me already

I think the first guy is right
