Question

If 2n⁄3 − 21⁄2 = 31⁄2, find the value of n.

Answer 1

Answer:

n=39

Step-by-step explanation:

2n⁄3 − 21⁄2 = 31⁄2

=2n⁄3  = 31⁄2 + 21⁄2

=2n⁄3 = 52/2

=2n⁄3 =26

=2n = 26 X 3

=n=26 X 3/2

n= 39

Answer 2

Answer:

N= 39

Step-by-step explanation:

2n⁄3 − 21⁄2 = 31⁄2

2n⁄3 = 21⁄2 - 31⁄2

21/

2

+31/2  =         21 + 31      

                                2

= 52/2  

=    52 ÷ 2  

= 2 ÷ 2

Now it is equals to 26 so

          2n           - 26

           3

now 3 * 26 =78

2n/78

now         2 ( 39)      

                78

there is an hidden sign between  2 ( 39)   which is * so 2 * 39 = 78

now it is 78/78  

you got the answer

n= 39

now why did i take 39 because 78/2 is 39 soo i took
