Approximately how many times greater is 6 x 10^-5 than 5 x 10^-9

8_murik_8 [283]

Answer: $6 \times 10^{-5}$ is $1.2 \times 10^4.$ times greater than $5 \times 10^{-9}$ .

Step-by-step explanation:

We are given two numbers.

First number : $6 \times 10^{-5}$ .

Second number : $5 \times 10^{-9}$ .

In order to find how many times $6 \times 10^{-5}$ is greater than $5 \times 10^{-9}$ , we need to divide first number by second number.

Therefore,

$6 \times 10^{-5}$ ÷ $5 \times 10^{-9}$

or $\frac{6 \times 10^{-5}}{5 \times 10^{-9}}$

First we would divide 6 by 5.

On dividing 6 by 5, we get 1.2.

Now, we would divide 10^-5 by 10^-9.

In order to divide them, we can apply quotient rule of exponents $\frac{a^m}{a^n} =a^{m-n}$ .

We get

$\frac{10^{-5}}{10^{-9}} = 10^{-5-(-9)} = 10^{-5+9} = 10^4$ .

Therefore,

$\frac{6 \times 10^{-5}}{5 \times 10^{-9}}$ = $1.2 \times 10^4.$

So, we could say finally $6 \times 10^{-5}$ is $1.2 \times 10^4.$ times greater than $5 \times 10^{-9}$ .

Completely simplified the expression for x plus 10 plus 6 x plus 2 x by combining like terms into your answer in the box.

siniylev [52]

We can first turn the text into a proper formula:

x plus 10 plus 6 x plus 2 x

x+10+6x+2x

The like terms are the numbers with

We can then put the like terms together to continue the calculation:

x+6x+2x+10

=9x + 10

Therefore, the answer is 9x + 10.

Hope it helps!
