The sales tax $950 item would be $57. Hope this helps!
This is equal to:
(8.9*4)(10^4*10^8)
pertinent rule: (a^b)(a^c)=a^(b+c)
(8.9*4)(10^12)
35.6X10^12
3.56X10^13 (and if we kept only significant figures....)
3.6X10^13
Hello from MrBillDoesMath!
Answer:
-5, 0 (multiplicity 2), +4
Discussion:
Let f(x) = x^4 + x ^3 - 20 x^2
Factor x^2 from each term:
f(x) = x^2 ( x^2 + x - 20) = x^2 ( x +5) (x-4)
f = 0 when x = 0 (multiplicity 2) and x = -5 or x = 4

MrB
