Today in class Mrs. Armstrong showed us how to use the html codes for this blog:
    • Exponents: x< .sup>1/2 (no spaces and periods)
    • Square root: < .sqrt >x+2< /sqrt > (no spaces and periods)
We also corrected some questions in Ex:21

Egs:

1) 38= what number times it self 3 times will give 8
3 8 = 81/3
3 8 = 2

6) 343 = 31/231/4
= 32/4+1/4 = 33/4 = 433

How to do it on the calulator:

Option 1 8yx 0.3333333 = 1.9999999.... (not accurate)
Option 2 8yx 1 ab/c = 2 (only if you have the ab/c button on your calulator)

COMMON PERFECT SQUARES AND CUBES TABLE



Heres an link that will show you the laws of rational exponents

Homework: finishing the puzzle Mrs. Armstrong gave us

Important!!!! On Monday we have a Quiz!!
The person who is going to blog next is...... Eden!
