Question

If g' = 167+2, what is the value of y?
O -8
o 4
o – 2
O-1

Answer 1

`A) \: -8`

Explanation:

`8^y=16^(y+2)`

⟹ Apply exponent rule:-

`3y=4\left(y+2\right)`

Expand:-

`3y=4y+8`

⟹ Subtract 4y from both sides:-

`3y-4y=4y+8-4y`

`-y=8`

⟹ Divide both sides by -1:-

`(-y)/(-1)=(8)/(-1)`

`y=-8`
