Answer:

k=2/3

Step-by-step explanation:

Step 1:

Step 1 in solving the exponential equations is re-writing the base same as other side of the equation

so,

$25^{3k}=625\\=> 25^{3k}=25^2$

Step 2:

Second step is equating the exponents

The rule used is:

$If\ B^m=B^n\ then\ m=n$

So in this case

$3k=2\\k = \frac{2}{3}$

So the solution is:

k=2/3 ..

Solve the quadratic equation x2 - x = 30 by completing the square

kap26 [50]

Answer:

Step-by-step explanation:

Given

x² - x = 30

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- $\frac{1}{2}$ )x + $\frac{1}{4}$ = 30 + $\frac{1}{4}$

(x - $\frac{1}{2}$ )² = $\frac{121}{4}$

Take the square root of both sides

x - $\frac{1}{2}$ = ± $\sqrt{\frac{121}{4} }$ = ± $\frac{11}{2}$

Add $\frac{1}{2}$ to both sides

x = $\frac{1}{2}$ ± $\frac{11}{2}$ , thus

x = $\frac{1}{2}$ - $\frac{11}{2}$ = - 5

x = $\frac{1}{2}$ + $\frac{11}{2}$ = 6
