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:

5 - 25, 2.5, 0,5√2,5π

1/2 - 5/2, 1/4, 0, √2/2, √2/4, 1/2*π

0- 0, 0,0,0,0,0

√2- 5√2, √2/2, 0, ,2, 1, 4.448

1/√2- 5√2/2, √2/4, 0, 1, 2.22

π- 5π, 1/2*π, 0, 4.448, 1/2, 9.861
