Midterm bc+cd-bd (-8)(-6)+(-6)(-3)+(-8)(-3) 48+18+24 = 90 I forgot to put a subtacting sign

2/3 / (-2/8) 2/3 / -1/6 = -4 I multiplyed and divide wrong 1/2 x+ 1/4x+12 1/2(10)+1/4(10)+12 5+2 1/4 + 12 19 1/4 i added wrong 1/3 and 2/4 4/12 + 6/12 = 10/12 = 5/6 i reduced wrong

You are baking cookies for a bake sale. You estimate that you will have about 7 1/2 hours to make them. It takes you 2./3 of of an hour to make each dozen. How many dozens cookies will you be able to bake?

(7 1/2)(2/3)(12)= 60 i multipled instead of adding

(23y)0 = 23y 1

i multplyed the number

__21 x3 y7 z2__ 24 x4 y3 z

__21 x y4 z__ 24

(3/4) -3= 4/3 3

Exponents

when the base is the same you just add the exponents, but when the base is different you leave it how it is you dont change it.

exponents are use to multiply the base by what the exponent is. For example if it is eight to the fifth power I multiply the number eight five times. You never go 8x5 big no no

3.3 Dividing Exponents

when you divide exponents you keep the base and subtract the exponents For example eight to the power of twelve divided by eight to the power of three so you will go 12-3 2ich equals eight to the power of nine.

3.4 power to a power when you use power to a power you keep the base and multiply the exponents For example (8 to the pwer of 5) to the power of 3 you will go 5x3 and it will equal eight to the power of 15__**
