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

How far is a chord of length 8 cm from the centre of a circle of radius 5 cm

ivann1987 [24]

Answer:

OB = 3 cm

Step-by-step explanation:

AO = radius = 5 cm

AB = 8cm/2 = 4 cm

Pythagora

OB² = AO² - AB²

= (5cm)² - (4cm)²

= 25cm² - 16cm²

= 9 cm²

OB = √9cm²

= 3 cm
