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 = 8^1/3
³ 8 = 2

6) 3⁴3 = 3^1/23^1/4
= 3^{2/4+1/4 = 3^3/4 = ⁴3³}^{How to do it on the calulator:

Option 1 8y^x 0.3333333 = 1.9999999.... (not accurate)
Option 2 8y^x 1 a^b/c = 2 (only if you have the a^b/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!}
