Question

HELP PLSSSSSS I NEED TO GET THIS DONE

Answer 1

1). a = 10, b = 6

2). a = 5, b = 3, c = 8

Explanation:

Given expression is,

1).
`(7^(6)* 7^8)/(7^4)` =
`(7^a)/(7^4)=7^4`

=
`(7^(2+8))/(7^4)` [Since
`x^(m)* x^n=x^((m+n))`]

=
`(7^(10))/(7^4)`

=
`7^{{10-4}}`

=
`7^(6)`

Therefore, a = 10 and b = 6

2).
`(2^5)/(4)=(2^5)/(2^a)=2^b=c`

=
`(2^5)/(2^2)`

=
`2^{{5-2}}`

=
`2^(3)`

= 8

Therefore, a = 5, b = 3 and c = 8
