Evaluate log3^8, given log3^2 is equivalent to 0.631

elixir [45]

We will use the followin property of logarithms:

$log(a^b) = b log(a)$

So, we have

$log(3^2) = 2 log(3) = 0.631$

If you multiply both sides by 4, you get

$8log(3) = log(3^8) = 2.524$

Answer:

The function is injective but nor surjective

Step-by-step explanation:

f(x) = x³

f(x) = x₁³ = x₂³ ⇒ x₁ = x₂, both are natural numbers

It it confirmed one-to-one, hence it is injective

<u>Check the surjectivity:</u>

f(x) = y ∈ N

x³ = y
y = ∛x

2 = x³
x = ∛2 ∉ N

Since x is not natural, the function is not surjective

9(5x + 1) ÷ 3y

alexdok [17]

The expression obtained after solving the given expression is, $\rm \frac{(15x+3)}{y}$

<h3>What is a BODMAS rule?</h3>

For the Bracket, Order, Division, Multiplication, Addition, and Subtraction rules, BODMAS stands for Bracket, Order, Division, Multiplication, Addition, and Subtraction.

Given expression ;

9(5x + 1) ÷ 3y

Follow the BODMAS rule;

Step 1; Divide

$\rm \frac{9(5x+1)}{3y} \\\\ \frac{3(5x+1)}{y} \\\\$

Step 2; Multiply

$\rm \frac{9(5x+1)}{3y} \\\\ \frac{(15x+3)}{y} \\\\$

Hence the expression obtained after solving the given expression is, $\rm \frac{(15x+3)}{y}$
