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

is times greater than .

Step-by-step explanation:

We are given two numbers.

First number  : .

Second number : .

In order to find how many times   is greater than , we need to divide first number by second number.

Therefore,

÷

or

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 .

We get

.

Therefore,

=

So, we could say finally is times greater than .

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
