Find the value of k when 5^-3 + 5^-4 = 5^k x 5^-4

k= 6/5 or 1.12

Step-by-step explanation:

You isolate the variable by dividing each side by factors that don't contain the variable. This variable (K) is not a whole number so I gave you the fraction and rounded decimal form. Hope this helps :)

Given , 1/2 is a solution of the equation

or, 1/4 - 5/4 = -k/2

or, -k/2 = -1

or k = 2

Step-by-step explanation:

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
