So it would be 4(x+2)1/4=4(x+2)3-2x-1/x+2 ?

1/4=3-2x-1/(x+2)

The LCD is 4(x+2)

where do I go from here?

So I recalculated with calculator and came up with 355.0488005, but we move 3 decimal points and get the increase after five years as .355 or rounded .36.

Is this correct?

S=2.35( ? )

Now do the indicated calculations. A calculator will be useful.

So I do what is in the parenthesis first which comes out to .0286 now mutiply this by 5 and the answer is 0.14. Is this correct?

I get to this part:

S=2.35(1+1.8/100)^5

S=2.35( ? )

S=2.35(1+1.8/100)^5

S=2.35( ? )

If the inflation rate in Italy is 1.80%, the item is expresso at 2.35 euros what would it be in 5 years?

The equation: S=C(1+R/100)^5

So it is: S=2.35(1+1.8/100)^5

Not sure how to calculate? Need to show my work so if you could help that would be wonderful.

L=2.43*W^0.3326, The weight is in pounds if 1 to 1.5 pounds, length is 14-20 inches. I understand that it is L=2.43 x 1 but what does ^ this mean?
