Question

1. which expression is equivalent to (1.1)^5? (round to the nearest tenth)

5.5
5.1
1.5
1.6

Explanation:

Step1: Expand the exponent

$(1.1)^5=1.1\times1.1\times1.1\times1.1\times1.1$

Step2: Perform the multi - plications

$1.1\times1.1 = 1.21$, then $1.21\times1.1=1.331$, then $1.331\times1.1 = 1.4641$, then $1.4641\times1.1=1.61051$

Step3: Round to the nearest tenth

Rounding $1.61051$ to the nearest tenth gives $1.6$

Answer:

$1.6$
