Solving the equation and something to do with log

Anastaziya [24]

Answer:

m= 1/2.

Step-by-step explanation:

To solve this, we must make the bases equivalent. We can do this by finding the common base which is 5.

We know that 125= 5³ and 25=5², which will help us in this equation. We can rewrite the equation substituting this for the original numbers:

$5^{3(2m)} = 5^{2(m+1)}$ Distribute the exponents to get:

$5^{6m} = 5^{2m+2}$

Now, we can simply ignore the '5' and solve for 'm':

6m= 2m+2

4m= 2

m= 1/2.

Factor the polynomial <br>64x^3-125

kobusy [5.1K]

$64 x^{3} -125$

= $(4x)^{3} - 5^{3}$ ------> because, $(4x)^{3}$ is same as 64x³ and
$5^{3}$ is same as 125

Using the formula: $a^{3}- b^{3} =(a-b)(a ^{2} +ab+b ^{2} )$ , we get,

= $(4x -5)((4x)^{2} +4x*5+ 5^{2} )$

= $(4x -5)(16 x^{2} +20x+25)$ ------>that's your answer!!

Answer:

r= 6p + 20

Step-by-step explanation:

given:

r= 3n + 20

also given that n = 2p

substituting n=2p into the above equation

r= 3n + 20

r= 3(2p) + 20

r= 6p + 20
