Write ln x^2+3 iny a single logarithm (picture provided)

option a.

Step-by-step explanation:

To solve the given exercise nad write the expression as a single logarithm, you must keep on mind the following properties:

Therefore, by applying the properties shown above, you can rewrite the expression given, as following:

Then, the answer is the option a.

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
