Heya,

(6/7)^4z × (6/7)^-3 = (6/7)^5

On equating the exponents we get,

4z + (-3)= 5
=> 4z = 5+3
=> z = 8/4
=> z = 2 ANSWER...

HOPE IT HELPS:-))

ClaryHerondale: you've done a mistake sweetie

ClaryHerondale: you should add the powers

Prateek240: Listen, There is 3 not -3.

Prateek240: So what is answer

Answered by ClaryHerondale

${ \frac{6}{7} }^{4z} \times { \frac{6}{7} }^{ - 3} = { \frac{6}{7} }^{5} \\$
Taking the powers as the base is common,

4z+(-3)=5
4z =8
z = 2

ClaryHerondale: and you want 6/7

Prateek240: Oh i got it

Prateek240: thx thx

ClaryHerondale: and 7/6 is exactly the same thing as (6/7)^-1

ClaryHerondale: you're welcome

Hunter21: M sorry

Hunter21: U r right

Hunter21: If it was 6/7 to the power 3 then my ans was ryt

ClaryHerondale: yeah, But it's not that way

Hunter21: :)
