viva [34]

Answer:

$\ln(\frac{x^3}{y^8})$

Step-by-step explanation:

$3 \ln(x)-8\ln(y)$ is the given.

The instructions is to write as a single logarithm.

Let's use the power rule first:

$\ln(x^3)-\ln(y^8)$

Now we see the minus between the natural logs so we can use the quotient rule:

$\ln(\frac{x^3}{y^8})$

Answer:

2.

r + 7 = 13

r = 13 - 7

r = 6

4.

12 - c = 3

-c = 3 - 12

-c = -9

c = 9

6.

5 + x = 14

x = 14 - 5

x = 9

8.

14 - x = 0

-x = 0 - 14

-x = -14

x = 14

10.

b + 7 > 8

b > 8 - 7

b > 1

12.

m - 4 < 7

m < 7 + 4

m < 11

14.

4 + q < 13

q < 13 - 4

q < 9

16.

s + 0 < 5

s < 5

18.

h - 7 > 7

h > 7 + 7

h > 14

densk [106]

Answer:

Area = $\frac{75}{4} \sqrt{15} sq mm$

Step-by-step explanation:

Here we are given with all the sides of the triangle , and we are asked to find the area of it. we will use Heron's Formula to find the area. The formula is as under

Area $= \sqrt{s\times (s-a) \times (s-b) \times (s-c)}$
