Question

I will give metals

Answer 1

@ganeshie8

Answer 2

\[64^5\]

Answer 3

can you help me with two others?

Answer 4

\[x^{(a-b)} = x ^a / x^ b\]

Answer 5

Sure!

Answer 6

Take a look at these rules and see if you can figure it out from them: http://math2.org/math/algebra/exponents.htm

Answer 7

Let me know if you need help from there.

Answer 8

I think for 1 A and 2 D?

Answer 9

\[x^{a}* x ^{b} = x ^{(a+b)}\]

Answer 10

so for 1: \[4^{3}*4^{4} = 4^{(3+4)}=4^{7}\neq4^{12}\], so the answer is not A. Can you see it now?

Answer 11

so for one I think b?

Answer 12

Why b?

Answer 13

because 3+2 is 5

Answer 14

but is \[5^{5} > 5^{5}\]?

Answer 15

no it would be = ?

Answer 16

That's right!

Answer 17

So which one is false?

Answer 18

Sorry I mean true ;)

Answer 19

c!!

Answer 20

you got it!

ok so for 2 it would be a?

Answer 22

yup!

Answer 23

thank you. can you help me with another

Answer 24

Sure!

Answer 25

What's \[x(5x)\] ?

Answer 26

5x^2??

Answer 27

yes! so what is \[-x(5x)\] ?

Answer 28

-5x^2

Answer 29

yup. so then what is \[-x(-4)\]?

Answer 30

4x

Answer 31

so put those two together.

Answer 32

D?

Answer 33

you got it!

Answer 34

Thank you!!

Answer 35

no problem!

Answer 36

ok shoot!

Answer 38

What's 1.4*8?

Answer 39

11.2?

Answer 40

yes

Answer 41

What's \[10^{1}*10^{4}\]?

Answer 42

100000

Answer 43

do you know what that is in exponential form?

Answer 44

10^4??? or 10^5?

Answer 45

Which one?

Answer 46

Remember the equation \[x ^{a}*x ^{b}=x ^{(a+b)}\]?

Answer 47

so 10^5

Answer 48

yes. another way to determine that is to count the number of zero's.

Answer 49

so what do we get when we put those two parts together?

Answer 50

c

Answer 51

Close.

Answer 52

You would get \[11.2*10^{5}\]
which is equal to what?

Answer 53

When you move the decimal point one place to the left, what do you do with the exponent?

Answer 54

1.12

Answer 55

and what does the \[10^{5}\] become?

Answer 56

try it on a calculator. \[11.2*10^{5} = 1.12*10^{?}\]

Answer 57

10^4

Answer 58

oops I mean 10^6

Answer 59

that's it! do you understand how that works?

Answer 60

yes thank you so much
