Question

pls answer its it's very important​

Answer 1

26

${ (\frac{6}{7} )}^{4} \times {( \frac{6}{7} )}^{ - 9} = {( \frac{6}{7}) }^{2m - 1} \\ { (\frac{6}{7}) }^{4 - 9} = {( \frac{6}{7}) }^{2m - 1} \\ - 5 = 2m - 1 \\ - 4 = 2m \\ m = - 2$

hope it helps you

Answer 2

Answer:

m=-2

Step-by-step explanation:

Exponent addition says that x^a * x^b = x^a+b

So, this means that first equation is equal to (6/7)^-5

You then want to set the second exponent equal to that since the (6/7) is already equal to (6/7).

2m-1=-5

Add 1 to both sides

2m=-4

divide by two on both sides

m=-2
