How is a•b different from a^b?

Exponents

Poll

Which option do you think is better?

Option A, getting 2+4+6+8...and repeating the pattern for 30 days

Option B getting .02+.04+.8+1.6...and repeating the pattern for 30 days

They are the same

Open Ended

Why did you pick the option you did?

Type response here

Multiple Choice

How would you represent what is happening for option A? (That was the one that started with getting $2.)

2+4+6+8+10+12...all the way to +60

2⋅30

2(1+30)

2⋅2⋅3⋅4...all the way to 30

Multiple Choice

How would you represent option B? (the one that started with 2 cents)

2¹+2²+2³+2⁴+2⁵all the way to 2³⁰

2³⁰

2¹⋅2²⋅2³⋅2⁴⋅2⁵

2²+2² +2²...27 more times

Poll

Which would you pick?

Still A

Still B

Changed to A

Changed to B

Let's add up the numbers in the sequence:

2+4+6+8+10+12+14+16+18+20+22+24+26+28+30+32+34+36+38+40+42+44+46+48+50+52+54+56+58+60=

When we add these numbers together, we get:

930

That was in dollars so option A got you $930

2³⁰=1,073,741,824 One billion seventy-three million seven hundred forty-one thousand eight hundred twenty-four

But remember that was 2 cents so we divide it by 100

which is easy since dividing by 100 means you move the decimal 2 places to the left so

1,073,741,824 pennies =$10,737,418.24 which is
Ten million seven hundred thirty-seven thousand four hundred eighteen dollars and twenty-four cents.

Fill in the Blanks

$10,737,418.24 - $930 How much more was option B than option A?
