Question

Annabelle and Navene are multiplying (4275)(4372).



Annabelle's Work Navene's Work
(4275)(4372) = 42 + 375 + 2 = 4577 (4275)(4372) = 42⋅375⋅2 = 46710

Is either of them correct? Explain your reasoning.

Answer 1

(4^2 7^5) (4^3 7^2)= 4^2 + ^3 7^5+ ^2 = 4^5 7^7

Answer 2

annabele

Answer 3

now ima do navenes

Answer 4

what do the carets before the numbers mean?

Answer 5

for example what does ^3 mean?

Answer 6

(4^2 7^5) (4^3 7^2) = 4^2 x ^3 7^5 x ^2 = 4^6 7^10

Answer 7

sorry

Answer 8

@freckles it means like its an exponent so i guess its raised

Answer 9

hint:we can write this:
\[\large \left( {{4^2} \cdot {7^5}} \right)\left( {{4^3} \cdot {7^2}} \right) = \left( {{4^2} \cdot {4^3}} \right)\left( {{7^5} \cdot {7^2}} \right) = {4^{2 + 3}} \cdot {7^{5 + 2}} = ...?\]

Answer 10

like I know what 5^2 means this is 5*5
but I have no clue what something like ^3 means

Answer 11

the exponents are being added or also they are being multiplied in the other one

Answer 15

can u see it?

Answer 16

its #7

Answer 17

http://prntscr.com/89limo here what number is raising to the 3rd power
that's what she is asking

Answer 18

can u see the question?

Answer 19

no :(

ok wait a sec plz

Answer 29

@Michele_Laino @freckles

Answer 30

okay so 4^{3+2} use parentheses so we can understand otay :=)

Answer 31

ok:D

Answer 32

4^(5)

Answer 33

as I wrote before, your expression can be rewritten as below:
\[\large \left( {{4^2} \cdot {7^5}} \right)\left( {{4^3} \cdot {7^2}} \right) = \left( {{4^2} \cdot {4^3}} \right)\left( {{7^5} \cdot {7^2}} \right) = {4^{2 + 3}} \cdot {7^{5 + 2}} = ...?\]

Answer 34

when we multiply same bases we should add or multiply the exponents ?

Answer 35

add?

Answer 36

yes right

Answer 37

yes!

Answer 38

ok so michele its 4^(5) times 7^(7)

Answer 39

right?

Answer 40

yes!

Answer 41

so then when there not like bases how do u multiply it?

Answer 42

we have to compute the explicit value of each power and then we have to multiply them together

Answer 43

whaa?

Answer 44

then you can't
like for this one
\[2^2 \times 3^5 \]

Answer 45

you will not see question like that one ^^ hehe

Answer 46

lol

Answer 47

for example:
\[\large \begin{gathered}
\left( {{4^2} \cdot {7^5}} \right)\left( {{4^3} \cdot {7^2}} \right) = \left( {{4^2} \cdot {4^3}} \right)\left( {{7^5} \cdot {7^2}} \right) = {4^{2 + 3}} \cdot {7^{5 + 2}} = \hfill \\
\hfill \\
= 1024 \cdot 823543 = {\text{843}}{\text{,308}}{\text{,032}} \hfill \\
\end{gathered} \]

Answer 48

ok nnesha i didnt understand what u said above that

Answer 49

whoa!!

Answer 50

so u just multiply the bases and then the exponents together right?

Answer 51

you question is
when bases are not like
then how would we multiply it ?
if bases are not same you can't multiply or add the exponents \[2^2 \times 3^5= 2 \times 2 \times 3 \times 3 \times 3 \times 3 \times 3\]

Answer 52

no, I'm sorry, you have to evaluate each power first, then you have to multiply the obtained values together

Answer 53

ohh then you multiply all those together?

Answer 54

yes!

Answer 55

ooh

Answer 56

btw ur username is same as \[\huge\rm 7^5jeannie7^5\]

Answer 57

haha ^.^

Answer 58

so 972?

Answer 59

o^_^o

Answer 60

what 972 ?

Answer 61

multiplying all of them together

Answer 62

ohh the example i gave you ? yes

Answer 63

can you please do a summarry of the answer please? of the question lol

Answer 64

you already know
when we multiply same bases we should `add or multiply` their exponents ?

Answer 65

add

Answer 66

yes! right!
so who is right anna or Navene ?

Answer 67

ohh annabel

Answer 68

yes yayay! anna!

Answer 69

yayyyyy thx
