OpenStudy (kg1975):

i know

jhonyy9 (jhonyy9):

ok.

OpenStudy (kg1975):

\[\frac{ (5+3)^{2} }{ 1+2^{5}-23 }\]

OpenStudy (kg1975):

ok so ik peretheses first

jhonyy9 (jhonyy9):

yes but there is denominator bc. this is a fraction

OpenStudy (kg1975):

ok so what do i do first then? add all the denominators?!

jhonyy9 (jhonyy9):

how many will result there on denominator ?

jhonyy9 (jhonyy9):

2^5 = ?

OpenStudy (kg1975):

2*2*2*2*2?

jhonyy9 (jhonyy9):

yes equal ?

OpenStudy (kg1975):

32

jhonyy9 (jhonyy9):

ok - nice and there is in front of 2^5 an 1

OpenStudy (kg1975):

33

jhonyy9 (jhonyy9):

and there is again -23

OpenStudy (kg1975):

10

jhonyy9 (jhonyy9):

yes nice so this will be the resulted denominator so now what will get on numerator ?

OpenStudy (kg1975):

\[8^{2}\]

OpenStudy (kg1975):

8*8

jhonyy9 (jhonyy9):

yes sure so how many will be this ?

OpenStudy (kg1975):

64

jhonyy9 (jhonyy9):

exactly so you ve got this fraction simplified 64/10 = ?

OpenStudy (kg1975):

\[\frac{ 64 }{ 10 }\]

OpenStudy (kg1975):

idk what that =

jhonyy9 (jhonyy9):

64/10 = 6,4 but idk that you ve learned it again ?

OpenStudy (kg1975):

how can a fraction = 6.4?

jhonyy9 (jhonyy9):

than you divide 64 by 10 so result 6,4

OpenStudy (kg1975):

why would u divide a fraction?

OpenStudy (welshfella):

the .4 is known as a decimal - which is a fraction with denominator 10 or multiple of 10

OpenStudy (kg1975):

i do not understand this DX

OpenStudy (skullpatrol):

$$\huge a \div b = \dfrac{a}{b}$$

OpenStudy (welshfella):

1/2 = 5/10 = 0.5 or we could get the same result by dividing 1 by 2 because we have a counting system built on a0.

OpenStudy (welshfella):

* 10

OpenStudy (kg1975):

OHHHHHH!!!!! now it makes sense!!!!
