Question

Which shows the expression below simplified?
0.16 + (2.9 × 10-3)
A. 3.06 × 10-3
B. 3.06 × 10-4
C. 1.629 × 10-3
D. 1.629 × 10-1

Answer 1

The answer would be D
because \[0.16 + 2.9\times10^{-3}\] converted to standard form is
\[0.16 + 0.0029\] which equals \[0.1629\] then converted back to scientific notation would be \[1.629\times10^{-1}\]
