### Noelle Cuvos's Scribepost For December 8th

Hey Guys I'm one of the few scribers for today, and I was chosen to do 3 questions on page 85. The 3 questions were questions number 15, 16 and 23.

Question 15
Evaluate:
square root of:
a)49=7
b)64=8
c)652=25.2

To get all those answers, I simply used my calculator.

Question 16
Evaluate:
Square root of:
a)9=3
b)25=5
c)1600=40

Again to get those answers, I used my calculator.

Question 23
A helicopter landing pad has a square shape. The area is 400m squared. Use Prime factorization to fine the side length of the pad.

400
=200 x 2
=100 x 2 x 2
=50 x 2 x 2 x 2
=25 x 2 x 2 x 2 x 2
=5 x 5 x 2 x 2 x 2 x 2
400 = (5x2x2) x (5x2x2)
400 = 20 x 20
400 = 20 squared

Simple sentence : The landing pad has a side length of 20 meters.

THANKS , COMMENT !

Good job Noelle. I liked everything that you did. Everything was well explained and it was easy to understand. I liked how you use color. It was a very good scribe.

Now I know how to figure out a square root.
