Question

pls help will fan and medal

Answer 1

Hint*
\[\large a^{-b} = \frac{1}{a^b}\]

Answer 2

i dont understand it at all xD

Answer 3

Lol okay :P

So basically when you have a number raised to a negative exponent *as you do here* you want to get RID of that negative exponent....you want it positive!

To do that...utilize the formula I wrote about...it states "to turn a negative exponent positive...you simply take the reciprocal of the entire expression ...that means put it under 1 in a fraction

So here

\[\large a^{-b} = \frac{1}{a^b}\]

Your question

\[\large 7^{-3} = \frac{1}{7^3} = ?\]

Answer 4

... @pooja195 i dont understand this

Answer 5

what is 7*7*7 ?

Answer 6

Answer 7

Answer 12

I'll rewrite it too

\[\large \frac{1}{7^3} = \frac{1}{7\times 7 \times 7} = ?\]

Answer 13

You said 343 right? So just put that under 1
1/343

Answer 14

so 1/343

Answer 15

yes

Answer 16

so not negative?

Answer 17

No the goal is to keep it positive we like to be happy ;)

Answer 18

*to make it

Answer 19

cx
there is 4 more if u can help

Answer 20

Sure

Answer 21

We want to make it positive
so we move it up the stairs so
5^5/1
5 x 5 x 5 x 5 x 5 =?

Answer 22

3125?

Answer 23

ok ;-;

Answer 24

Yes so it would just be 3125 as your answer

Answer 25

kk thx

Answer 26

post your next one

Answer 27

For this one:

\(\sf\Large \frac{a}{b^{-c}} = a \times b^c\)

Just plug in the numbers that you were given in the question. :)
a = 2
b = 4
c = 3

Answer 28

2x4^3 ?

Answer 29

..... @TheSmartOne

Answer 30

correct

so what is \(\sf\Large 2 \times 4\times 4 \times 4= ?\)
