A couple of quick ones?

[Flower9]

1.A duplicating machine enlarges a picture 30%. If that enlarger is used 2 times, about how many times as large as the original picture will the final picture be?


2.Simplify

x13/x6

Thank you!

With "1" being "100% of the regular size", what will the size be after one enlargement? Then apply the same multiplication to this result to get the size after a second enlargement. Compare the result with "1" to find the total final enlargement.

2.Simplify x13/x6

Does this actually mean "(x^13)/(x^6)" (that is, "x¹³/x⁶")? If so, just expand, cancel off the common factors, and collapse the result back into exponential notation. For instance:

. . . . .m⁵/m⁷ = [mmmmm] / [mmmmmmm] = 1/[mm] = 1/m²

If you mean 2 more times: (1.3)^3

2.Simplify
x13/x6

If x^13 / x^6: hint: 1 / a^b = a^(-b)

Next time SHOW your work...
