Question

How many zeros will be in the standard form of the exponential expression ten to the ninety-ninth power? ten zeros ninety-eight zeros ninety-nine zeros one hundred zeros

Answer 1

So, do you have an idea of how to start this?

Answer 2

no

Answer 3

Alright then. we'll do a similar kind of problem that perhaps isn't quite so large.

10^2 = 100. The exponent will dictate how many zeros you have after the 1. Make sense?

Answer 4

Because 10 multiplied by 10 is 100.

Answer 5

Or 10^3, will have 3 zeros for 1000.

Answer 6

so whats the answer

Answer 7

If the exponent in your problem is 99, how many zeros do you think your problem will have?

Answer 8

Think of it like this,

\(\large{10^{99}\Rightarrow (10)_1(10)_2(10)_3\cdot\cdot\cdot(10)_{99}}\)

When you multiply anything by 10, you simply add on a zero to the end. Knowing this, what do you think is the answer?

Answer 9

so its 99

Answer 10

Right. :)

Answer 11

Answer 14

Suppose your friend starts a rumor by telling you some juicy gossip Sunday night. On Monday, one of you shares the gossip with 2 more friends. The next day, they each share the rumor with 2 of their friends, so 4 more people hear the rumor on Tuesday. On Wednesday, those people each share the rumor with 2 of their friends, so now 8 more people have heard the rumor.

If the rumor continues to spread this way, how many people will hear the rumor on Saturday?

sixteen

thirty-two

sixty-four

one hundred twenty-eight

Answer 15

Oh okay.
So let's make a table so we can see these numbers better. Sound cool?

Answer 16

yeah

Answer 17

The numbers are the amount of people know the rumor on each day. What do you notice about these numbers?
