What is the following is the solution to the equation 25^(z+2) = 125

maksim [4K]

First, rewrite the equation $25^{z+2} = 125$ with the base equal to 5. Note that:

$25=5^2;$
$125=5^3;$
$25^{z+2}=(5^2)^{z+2}=5^{2\cdot (z+2)}.$

Then

$5^{2\cdot (z+2)}=5^3.$

Since the bases are equal, you have that powers are equal too:

$2\cdot (z+2)=3,\\ \\2z+4=3,\\ \\2z=3-4,\\ \\2z=-1,\\ \\z=-\dfrac{1}{2}.$

Answer: $z=-\dfrac{1}{2}.$

scoundrel [369]

Answer:

Step-by-step explanation:

if (h,k) is the center and r be radius of circle.

Then eq. of circle is (x-h)^2+(y-k)^2=r^2

reqd. eq. of circle is (x+4)²+(y+5)²=(√6)²

or (x+4)²+(y+5)²=6
