Question

Help me please my exam is going

Answer 1

Answer:

m = -5

Step-by-step explanation:

this chapter is of Exponents if I'm not wrong

then,

(-5)^m-1 ÷ (-5)^2 = (-5)^-8

(-5)^m-1-2 = (-5)^-8 ( applying the same base formula to the equation)[(a)^n÷(a)^n= (a)^n-n]

therefore,

(-5)^m-3=(-5)^-8

m-3 = -8 (taking only the Exponents)

m = -8 +3

therefore, m = -5
