Use the properties of logarithms to prove log, 1000 = log2 10.

Leto [7]

Given:

Consider the equation is:

$\log_81000=\log_210$

To prove:

$\log_81000=\log_210$ by using the properties of logarithms.

Solution:

We have,

$\log_81000=\log_210$

Taking left hand side (LHS), we get

$LHS=\log_81000$

$LHS=\dfrac{\log 1000}{\log 8}$ $\left[\because \log_ab=\dfrac{\log_x a}{\log_x b}\right]$

$LHS=\dfrac{\log (10)^3}{\log 2^3}$

$LHS=\dfrac{3\log 10}{3\log 2}$ $[\because \log x^n=n\log x]$

$LHS=\dfrac{\log 10}{\log 2}$

$LHS=\log_210$ $\left[\because \log_ab=\dfrac{\log_x a}{\log_x b}\right]$

$LHS=RHS$

Hence proved.

The Distributive Property allows you to say that 3(x − 1) = 3x −

Serga [27]

Answer:

$3x - 3$

Step-by-step explanation:

In the distributive property each value inside the parenthesis will be multiplied by the value outside the parenthesis.

In the expression 3(x - 1) it will look like:

$(3 . x) - (3 . 1)$

Then we multiply both value separately giving us:

$3x - 3$

So in conclusion it would be right to assume that.

$3(x - 1) = 3x - 3$

What are the expressions to fin the radius of an object having a circumference of 46 feet

dolphi86 [110]

Since the equation for solving circumference is 2 $\pi$ r, you can see that 2 $\pi$ r = 46. Dividing 2 $\pi$ on both sides will give you r, or the radius.
Hope this helped! :)
