Week 3 we just get into a new unit about absolute value and radicals, and we learned absolute Value of a real number and simplifying radical expressions. Also we did a test of first unit Sequences and series. The absolute value of a real number a is denoted by. a. and it is the distance from a to the origin 0 on the number line. The absolute value is always positive. Simplifying radical expressions step: Step 1: Find the prime factorization of the number inside the radical. Step 1: Find the prime factorization of the number inside the radical. Step 2: Determine the index of the radical. In this case, the index is two because it is a square root, which means we need two of a kind. Step 3: Move each group of numbers or variables from inside the radical to outside the radical. In this case, the pair of 2’s and 3’s moved outside the radical. Step 4: Simplify the expressions both inside and outside the radical by multiplying.

Week 2 in Math 11
This week is the second week in math 11. We learned Geometric Sequences and Geometric Series. A Geometric Sequence is a sequence in which the ratio of the common terms is equal and a Geometric Series is a series with a constant ratio between successive terms. For example, the series. Also, we learned how to input code in Edblogs for example, .
Week 1 – My Arithmetic Sequence
S=+ …..
= 20
Common difference: + 10
What’s the and What’s the

Solution:

*
=+(n-1)d
=20+(250-1)10=2510
*
*
*
=20
=20+20+(10)=50
=20+20+(10)+20+(10)+(10)=90
=20+20+(10)+20+(10)+(10)+20+(10)+(10)+(10)=140
*
*
*
= 20+20+(10)+20+(10)+(10)+20+(10)+(10)+(10)+***
= x (20 + 510)
= x 530
=56250
In conclusion, = 2510 and = 56250
