Answer 1

$\huge{\mathfrak{\green{S}}}{\mathfrak{o}}{\mathfrak {\orange {l}}}{\mathfrak{\red{u}}}{\mathfrak {\pink {t}}}{\mathfrak{\blue{i}}}{\mathfrak{\purple {o}}}{\mathfrak {\gray {n}}}$

➠ Let's round the value to the nearest hundredth.

➠ As wee can see, the digit 8 is in the thousandths place and is greater than 5.

➠ Therefore, you must round up to 0.038.

➠ Now express the value as a single digit times a power of 10, as following.

$\sf[3838 x10^{-3}]$

➠ Therefore, the answer is $\sf3838 x10^{-3}$
