The number of arrangements of the books is an illustration of permutation

The books can be arranged in 5040 ways

<h3>How to determine the number of arrangements?</h3>

The given parameters are:

  • Total books, n = 10
  • Books to arrange, r = 4

The number of arrangements is calculated as:

Ways = nPr

Substitute the given values

Ways = ¹⁰P₄

Apply the permutation formula

Ways = 10!/(10 - 4)!

Evaluate the quotient

Ways = 5040

Hence, the books can be arranged in 5040 ways

What is 1,000,000,000,000 as a power of 10?
alexandr1967 [171]

Answer:

1,000,000,000 as a power of 10, is: 10^12

Step-by-step Solution:

We can expand 1,000,000,000, and write this number as a multiplication sentence using only the number 10. By doing this, we can count the number of tens needed to be multiplied to get to his answer:

1,000,000,000 = 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10  

Since 10 is multiplied by itself 12 times, we can therefore say that 10^12 is equal to 1,000,000,000

Answer: n⁴+10n²x+25x²

Step-by-step explanation:

I don;t know how I can use the binomial squares pattern on Brainly, but I can definitely guide you through the problem.

(n²+5x)²                           [rewrite this from the squared]

(n²+5x)(n²+5x)                [use FOIL to expand]

n⁴+5n²x+5n²x+25x²       [combine like terms]

n⁴+10n²x+25x²
