You want one non-zero digit in front of the decimal. Count how many times the decimal must move to be behind the first non-zero digit. This is the power on the ten. If it moves to the left, the power is negative. If you must move it to the right it is positive.

I counted 7 moves to get to behind the 6.

Now all we have to do is replace N by 4
N! = 4(4-1)(4-2)
    = (4)(3)(4-2)

Write the set of non-negative integers in the inequality 2x &lt; 4.
Leviafan [203]

Answer:

The set S of non-negative integers in the inequality 2x < 4 is

S = \{0, 1\}

Step-by-step explanation:

The non-negative integers are given as \mathbb{Z}_{\ge 0} = \{ 0, 1, 2, \ldots \}

For the inequality 2x < 4, we have

2x < 4 \implies x < \dfrac{4}{2}  \implies  x < 2

Therefore,

x\in \mathbb{R}:x\in(\infty, 2)

Note: 2 is not included

The integers are

\ldots -2, -1, 0, 1

And the non-negative integers are

0, 1
