Question

If (82)p = 84, what is the value of p?

Answer 1

Divide both the sides by \(82\) to find \(p\)..

Answer 2

ok

Answer 3

No ok.. Just do it and show me what you did actually..

Answer 4

2? dont you mean subtract?

Answer 5

No, I mean divide..

Answer 6

1.024.. if i divide

Answer 7

If (8^2)p = 84, what is the value of p? nevermind this is the problem sorry

Answer 8

i just looked at it

Answer 9

Oh..

Answer 10

sorry

Answer 11

@NightCrawlers_

Answer 12

Tell me :
\(8^2 = ??\)

Answer 13

She looks like she got this ^

Answer 14

She? Who is she here?

Answer 15

Oh he?

Answer 16

ok back to the question

Answer 17

Who is he here now?

Answer 18

\[(8^{2})^{p}=84\]

Answer 19

thats the question

Answer 20

Hey man..!! First write your question properly.
Is that fine now? Is that now a right question?

Answer 21

p= A2 B3 C4 D6

Answer 22

yes it is

Answer 23

your question is still wrong..

Answer 24

what do you mean

Answer 25

It must be then:
\[(8^2)^p = 8^4\]

Answer 26

Otherwise, you won't get integer value for \(p\)..

Answer 27

yes.

Answer 28

but how would i work this out?

Answer 29

See, when bases are same, exponents are equal.

Answer 30

\[(a)^b = (a)^c \implies b = c\]

Answer 31

p=2 then?

Answer 32

Good.. Have you guessed it?

Answer 33

yes sadly

Answer 34

i wanna know how i did it or how to do it

Answer 35

See, you need to just make the base look equal on both the sides..

Answer 36

For that, look here, we have one power rule property:
\[(a^b)^c = (a)^{b \times c}\]

Answer 37

Now using it can I write :
\[(8)^4 = (8)^{2 \times 2} \implies (8^2)^2\]
See, this it is just a crystal clear use of that property..

Answer 38

\[(8^{2})^{2}=8^{4} so then 8^{2} x ^{2}=8^{4}\]

Answer 39

That is not \(x^2\), but there should be \(8^2\) instead of that..

Answer 40

what i just wrote but better haha

Answer 41

x=multiply

Answer 42

p=2

Answer 43

thank you

Answer 44

You can write it the best way as:
\[(8^{2})^{2}=8^{4} \quad \text{so then} \quad 8^{2} \times 8 ^{2}=8^{4}\]

Answer 45

ok thanks
