it is 4/5

   0.0000015390771693=80,927/52,581,508,981      

round it off baby that's base on what i have learned

8/10 is correct, but this is 4/5 not 2/5.

0.8 = \(0.8 = {8 \over 10} \)

or  \(0.8 = {2 \over 5} \)

And Thank You, it was what I need i Just one step dont understand but now I get it :) thanks

I started there but the next step must be what I write first.

There is no equal sign in your original question - it was a divide!

log2(n4)+5n=(n*log2(n))

\(log_2(n^4)+5n=(n*log_2(n))\\ log_2(n^4)+5n=log_2(n^n)\\ 5n=log_2(n^n)-log_2(n^4)\\ 5n=log_2(\frac{n^n}{ n^4 })\\ 5n=log_2(n^{n-4})\\ 2^{5n}=2^{log_2(n^{n-4})}\\ 2^{5n}=n^{n-4}\\ 32^n=n^{n-4}\\\)

Again, I suggest you have written the question down wrongly!

Started log2(n4)+5n=(n*log2(n)) so I hope they are right
How didi you het rid of that upper log₂(n)? and how seperate that 4/n when n is * and 4 is + with the rest

((log2(n^4)+5*n)/(n*log2(n))) 

\(n\ne0\)

\(\frac{log_2(n^4)+5n}{nlog_2(n)}\\ =\frac{4log_2(n)+5n}{nlog_2(n)}\\ =\frac{4}{n}+\frac{5}{log_2(n)}\\\)

Are you sure the brackets were in the right spots?

\(\frac{7.4*10^6}{6.8*10^-6} = \frac{7.4}{6.8}*\frac{10^6}{10^-6}\)

7.4 / 6.8 is approximately 1.088. This multiplied by the second part is 1.088 * 10^12. After rounding to 1 significant figure, you would get 1 * 10^12

27 = 9x

27/9 = 9x/9

x = 3

if you mean y = 3* (-2) - 2, then y = -8

but you mean y = 3* (-2)(-2), then y = 12

What is sinx equal to?

What are you trying to find the simplest form of?

There are no designated value for x or other information, so 5/x = 5/x

HOW DID YOU GET THE SIX PLEASE ANS ASAP!!THANKS

the answer is 2,700,000 homes.

43+5 = 8c -5 +5 (add 5 to both sides to get 8c by itself)

48/8 = 8c/8   (divide both sides by 8 to get c by itself)

6 = c

1/2 (22) (23)

.5*22*23 = 253

cot = 1/ tan

cot 51 = 1/ tan 51

1/tan(51) = 0.8097840331950409

What are you asking for?

14-41 = -27

It depends where you are asked to round from.

If it is to the nearest tens place then your answer is 570

If it is to the nearest hundred then your answer is 600.
