Okay...since people don't copy things down *cough* Preet .... uh .. yeah. [r] stands for radical. Anything inside the [] is under the radical. (e) is exponent. Ex. (e3) is something to the third power. Got it? Good. Cause here it comes:
12.1 > Sqare Root of a Number
1) Define "principle root"
2) Find [r121]
3) Find [r16/64]
4) Approximate [r79] to the nearest 10th
5) Find the side of the square whose area is 35cm(e2)
12.2 > The Set of Real Numbers
6) What is the difference between ration and irrational?
7) What is the difference between repeating decimals and terminal decimals?
8) What kind of decimal is 5/11?
9) What kind of decimal is 22/7?
10) Is 2/3 rational or irrational?
12.3 > Simplifing Rationals
11) Simplify [r3] x [r11]
12) Simplify [r28]
13) Simplify 5[r48]
12.4 > Radicals and Variables
14) Simplify [r36a(e3)b(e8)c(e7)] (i know this looks really confusing but look closer and it makes sense xD
15) Simplify 4x(e2)y(e3)[r4x(e5)z(e8)]
12.5 > Adding and Subtracting Radicals
16) Simplify 6[r20] - 3[r45] + [r80]
12.6 > Multiplying and Dividing Radicals
17) -8[r5(e5)] (3[r10x(e4) - 2[r4x(e4)] (in word form this is negative eight radical five to the fifth times three radical ten x to the fourth minus three radical forty five plus radical eighty)
18) [r96a(e9)] DIVIDED BY [r2a(e3)]
12.7 > The Pythagorean Theorm
19) In the right triangle, the length of the hypotnuse is 12 and the length of one leg is 8. Find the length of the other leg.
20) The length of a rectangle is 3 less than that twice the width. The premeter is 30. Find the length of a diagonal of the rectangle.
