No it's not,because 12 inches equals 1 foot and 2 feet equals 24 inches.
So 2 feet is bigger than 23 inches.

Answer:

Error: $lnx^2=ln 3x$ not $ln\frac{3x}{0}$

Solution:x=0 and 3

Step-by-step explanation:

We have to find the error and correct answer

Given: $2ln x=ln(3x)-[ln9-2ln(3)]$

$lnx^2=ln(3x)-[ln9-ln3^2]$

Using the formula

$alog b=logb^a$

$lnx^2=ln(3x)-[ln9-ln9]$

$lnx^2=ln(3x)-0$

$lnx^2=ln(3x)$

$x^2=3x$

$x^2-3x=0$

$x(x-3)=0$

Therefore, x=0 and x=3

But last step in the given solution

$lnx^2=ln\frac{3x}{0}=\infty$

It is wrong this property is used when

$log m-log n$ then

$log\frac{m}{n}$

Hence, the student wrote $lnx^2=ln\frac{3x}{0}$ instead of $lnx^2=ln3x$ and solution is given by

x=0 and x=3

Define reductionism i m so boredd

Sidana [21]

Step-by-step explanation:

Reductionism is a theory in psychology centered on reducing complex phenomena into their most basic parts. It is often contrasted with holism, which is focused on looking at things as a whole.

The purpose of reductionism is to simplify psychological events and processes by looking at their smallest elements, thus “reducing” something rather complex into its most simple.
