How do you write 1.5 × 104 in standard form?
rewona [7]
I'm assuming you meant 1.5 × 10⁴. Remember, when we write in standard form, you need to use ^ to denote it's 'to the power of'. So it would be 1.5 × 10^4. 

I'm also assuming you meant in decimal form, because that's already in standard form.

However, the answer is 15,000. This is because you lose one zero when multiplying a decimal with one number after it. For each number after the decimal, you take off a zero. Therefore, the end number is 15,000.

Simplify <br> 7.2x10^3/1.8x10^7
spayn [35]

To simplify and solve this equation we must follow PEMDAS.

P=Parentheses

E=Exponents

M=Multiplication (from left to right)

D=Division (from left to right)

A=Addition

S=Substraction

We begin the process.

10^3=1000

10^7=10000000

New equation looks like this:

7.2*1000/1.8*10000000

We then multiply

7.2*1000= 7200

7200/1.8=4000

4000*10000000= 40000000000

<em>So our final answer is 40000000000.</em>

Hope this helps!

P.S. I forgot this was scientific notation and I solved it a different way. But both ways give the same answer. Let me know if you want the other method.

What is the value of this expression when n approaches infinity?
topjm [15]

ANSWER

C. 35

EXPLANATION

The given expression is:

15 - 35 -  \frac{85}{n}  + 55 +  \frac{75}{2n}  +  \frac{15}{2 {n}^{2} }

As

n \to \:  \infty

\frac{k}{n}  \to0

where k is a constant.

This implies that,

15 - 35 -  \frac{85}{n}  + 55 +  \frac{75}{2n}  +  \frac{15}{2 {n}^{2} }  = 15 - 35 -  0 + 55 +  0+  0 =35

The correct answer is C
