Question

i give metals and i will be your fan. What is the value of the expression 7^3?

Answer 1

@SolomonZelman @Nnesha

Answer 2

the exponents tells how many times you should multiply the base
2^4 = 2 times 2 times 2 times 2

Answer 3

343

Answer 4

the 4 is a negative

Answer 5

so -343

Answer 6

ohh then you should apply the exponent rule \[\huge\rm 7^{-3}\] like this ?

Answer 7

ya

Answer 8

\[\huge\rm x^{-m}=\frac{ 1 }{ x^m }\] flip the fraction
when u flip it , the sign of the exponent would change

Answer 9

yaah if its negitive then it will be -343

Answer 10

so \[1/343\]

Answer 11

yes right

Answer 12

can you help me with more

Answer 13

i'll try :=)

Answer 14

What is the value of the expression ? 1/5^-5

Answer 15

okay apply the same rule!

Answer 16

\[\huge\rm x^{-m}=\frac{ 1 }{ x^m }\] flip the fraction
when u flip it , the sign of the exponent would change

exponent is negative so ^^^^^^

Answer 17

3125 is the anwser

Answer 18

well don't use the calculator.

Answer 19

1/3125

Answer 20

no flip the fraction

Answer 21

how can you show me

Answer 22

okay if i have \[\huge\rm 2^{-2} =\frac{ 1 }{ 2^2 }\] i would flip the fraction and change the sign of exponent

Answer 23

so it would just be 3125

Answer 24

yes right i guess you don't have to find 5^5

Answer 25

are there answer choices ?

Answer 26

yes

Answer 27

okay then that's right

Answer 28

A. 1/3125
B.1/25
C.25
D.3125

Answer 29

ookay. then ur answer is correct :=)

Answer 30

so D

Answer 31

yes

Answer 32

What is the value of the expression

Answer 33

rewrite 4 in terms of base 2

Answer 34

here are the options

Answer 35

so 4/3

Answer 36

no..
here is an example
rewrite 9 in terms of base 3 = 3^2

Answer 37

we need to get the same base at the numerator and at the denominator.

Answer 38

OK

Answer 39

2^2=4

Answer 40

yes right \[\huge\rm \frac{ 2 }{ (2^2)^{-3} }\]
to solve that you need to know two exponent rules
first one is \[\huge\rm (x^m)^n=x^{m · n}\]
and then when we divide same bases we should `subtract` their exponents \[\large\rm \frac{ x^b }{x^c }=x^{b-c}\]

Answer 41

would it be 1/32

Answer 42

nope.

Answer 43

how did you get that ?

Answer 44

256

Answer 45

hmm how ?..

Answer 46

is it right

Answer 47

well plz show ur work so i can find where udid a mistake.

Answer 48

plz tell me if it is right or not first

Answer 49

well that's a guess

Answer 50

so it is not right is it

Answer 51

128

Answer 52

\[\huge\rm (2^2)^{-3}\] we should solve it
apply the exponent rule \[\huge\rm (x^m )^n =x^{m \times n}\] multiply the exponents

Answer 53

plz just tell me the answer i only have 2 more minutes to finish it

Answer 54

we can solve this in two minutes
i can't give u the answer plz try to understand

Answer 55

-64

Answer 56

no just multiply the exponents

Answer 57

5

Answer 58

\[\huge\rm (2^2)^{-3} =2^{2 \times -3}\] base would stay the same

Answer 59

no it's not 5

Answer 60

2 times -3 = ?
