Question

9^2+9°-1!= 3n, what is value of n​

Answer 1

Step-by-step explanation:

9^2+9^-1=3n

3^2×2+3^3×-1=3n

3^4+3^-3=3n

81+1/27=3n

2187/27=3n

2187/27×3=n

27=n

hope it's the right answer!!

Answer 2

Step 1:

9 degree is equals to 9• pie/180
= 9pie/180
=0.157

It’s approx

Ok now let’s start sum

Step 1

9^2 = 81
And 9 degree - 1= (-0.843)

Ok now

81-0.843 = 3n
80.157= 3n
n = 80.157/3
n = 26.719!

In order to find an factorial product you need an natural number but here we have answer of 26.719 which is a integer

So /that’s why this sun is wrong

Still you can try with approx value of 27!

27!
= n = 27

answer will be

1.x * 10^x

where x is n+1

= 1.28* 10^28

I hope it will help you

Thank you
