Question 7 • CA-Algebra I A – 6002
Which exponential functions have been simplified correctly? Check all that apply.
Answer
A
f (x) = 5 RootIndex 3 StartRoot 16 Endroot Superscript x Baseline = 5 (2 RootIndex 3 StartRoot 2 EndRoot) Superscript x
B
f (x) = 2.3 (8) Superscript one-half x Baseline = 2.3 (4) Superscript x
C
f (x) = 81 Superscript StartFraction x Over 4 EndFraction Baseline = 3 Superscript x
D
f (x) = three-fourths StartRoot 27 EndRoot Superscript x Baseline = three-fourths (3 StartRoot 3 EndRoot) Superscript x
E
f (x) = (24) Superscript one-third x Baseline = 2 (RootIndex 3 StartRoot 3 EndRoot) Superscript x
