On every question we will do by the law ---

When bases are same power are equated

1. -4-8 = 4n

-12 =4n

n=-3

2. -17-8= 2m+1

-15-1=2m

-16=2m

m=-8

3. -3 +10 =3m+1

7-1=3m

6=3m

m=2

4. 3m+1-15=m

3m-m=14

2m=14

m=7 Answer

Answer 2

Step-by-step explanation:

1)

According to indices , exponential form

1) -4 + ( -8) = 4m

or, -12 = 4m

or, m = - 3 answer

2) -17 + -8 = 2m +1

or, -24 = 2m

or, m = -12 answer
