Question

integer exponents
4+(-6)^0 -4^-1

Answer 1

please help :(

Answer 2

Do you wish to evaluate this?

Answer 3

what evaluate?

Answer 4

Meaning like simplify

Answer 5

anything to the zero power = 1.

a negative power is just the absolute value but in the numerator.

This gives you:

4 + 1 - 1/4

Answer 6

oh ya :D

Answer 7

oops line 2 i meant denominator

Answer 8

so that means anything that has 1 over it is 1 then that number in fraction? or evertyhting even if it had say 5 ?

Answer 9

Easier to say, what does 1/4 equal to when it is in decimal?

Answer 10

if you have a negative exponent, you make it positive and put number being raised in denominator.

\[2^{-5} = \frac{ 1 }{ 2^{5} }\]

Answer 11

0.25?

Answer 12

oh
but i need to make it decimal

Answer 13

plug into calculator

Answer 14

Yes. Since it is negative 1/4, it will be -0.25.

The expression will then be 4+(-6)-(-0.25)
Then you just simplify it.

Answer 15

u need to simplify it even more?

Answer 16

No, you have to simplify the given expression (that I provided).

Answer 17

isnt the answer -0.25?

Answer 18

No.
First, you do the addition, what do you then get?

Answer 19

we never did that we only get the decimal and thats all

Answer 20

I hope that you know that we are using the order of operations.

Answer 21

Are you aware of the order of operations?

Answer 22

no -0.25 is just the answer to -4^-1.

You are trying to solve 4+(-6)^0 -4^-1

so you need 4 + 1 and then -0.25

Answer 23

we arentt supposed to do that
ur confusing Me >.<

Answer 24

4+1=5

Answer 25

P for parenthesis
E for exponents
M for multiplication
D for division
A for addition
A for subtraction

Answer 26

I meant S

Answer 27

5 - 0.25 = 4.75

Answer 28

4-(-6)=-2
-2+(0.25)=-2.25

Answer 29

OHH ok

Answer 30

@piglet9

Answer 31

@calculusxy I think you got that wrong there buddy...

(-6)^0 is not -6

Answer 32

how about this.

Answer 33

\[3(-9)^{0}+4^{-2} \]

Answer 34

3(1) + 1/16 = 3.0625

Answer 35

isnt it 0.0625?

Answer 36

1/16 is 0.0625 but you have to add the 3

Answer 37

oh ya in the begging one right?

Answer 38

yes

Answer 39

how about this

Answer 40

\[6+(-5)^{-2} -(4=3)^{0} \]

Answer 41

I don't think you can have parentheses across the equals sign like that...

Answer 42

my bad its supposed to be +
