Answer 1

Favorite Answer

2^4 = 16. 3^7 = 2187. 4^2 = 16.

So you now have: (16 + 2187) / (729 - 16). 2203 / 713 = 3.09.

Answer 2

If you realize that 729 = 3^6, then the problem is easy because it becomes-

2^4 +3^1 - 4^2

16 + 3 - 16

Answer 3

(2^4 + 3^7) / (729 - 4^2)

(16 + 2187) / ( 729- 16)

(2203) / ( 713)

3.0897...

You could leave it as a fraction, or simplify it further and solve the fraction.

Answer 4

16+2187 / 729-16

2203 / 713

3.089761571

That's algebra?

Looks like simple math to me.

Use a caculator.

And if you ain't allowed to use one, you sure shouldn't be asking YA then, either.
