Can you divide the number 8,101,265,822,784 by 8 without using either long or short division?
LuckyWell [14K]
Yes. If we wanted to divide  104 by 8 we could write 104 as sum of multiples of 8 with which we are familiar:

104=80+24

then \frac{104}{8}= \frac{80+24}{8}= \frac{80}{8}+ \frac{24}{8}=10+3=13

We use the same procedure to divide the given number by 8:



First  We can "decompose" the number as a sum of multiples of 8 which we recognize easily. Then, divide each single one of them with 8.

That is 

 <span>8,101,265,822,784 = 8,000,000,000,000+100,000,000,000+1,000,000,000
</span>
+265,822,784

now decompose 265,822,784:

265,822,784=240,000,000+24,000,000+1,000,000+800,000+22,784

now decompose 22,784

22,784=16,000+6,784

decompose 6,784

6,784=6,400+384= 6,400+320+64


Thus:

 8,101,265,822,784 : 8 =(8,000,000,000,000+100,000,000,000+1,000,000,000+240,000,000
+24,000,000+1,000,000+800,000+16,000+6,400+320+64):8

=1,000,000,000,000+12,500,000,000+125,000,000+30,000,000+
3,000,000+125,000+100,000+2,000+800+40+8

=(1,000,000,000,000+12,500,000,000)+(125,000,000+30,000,000)
   + 3,227,848

=1,012,500,000,000+155,000,000+3,227,848

=1,012,655,000,000+3,227,848

=1,012,658,227,848

irinina [24]

Answer:

Real number 5

Imaginary number 5i

Complex number 2+5i

Step-by-step explanation:

A real number is that number that can be represented on number line

There is no imaginary part in real number

Example of real number is 5

Imaginary number is that in which there is no real part

Example of imaginary number is 5i

When there is a combination of both real and imaginary part then number is called complex number

Example of complex number is 2+5i

Analyze the diagram below and complete the instructions that follow.
Trava [24]

Law of Cosines says


b^2 = a^2 + c^2 - 2 ac \cos B


2 a c \cos B = a^2 + c^2 - b^2


\cos B = \dfrac{a^2 + c^2 - b^2}{2 a c}


\cos B = \dfrac{16^2 + 16^2 - 11^2}{2(16)(16)} = \dfrac{ 391}{512}


B = \arccos  \dfrac{ 391}{512} \approx 40.2 ^\circ


Choice C
