Question

community service during the school year, each student planted $1.2 \times 10^2$ flowers as part of a community service project. if there are $1.5 \times 10^3$ students in the school, how many flowers did they plant in total?\
\
\\(\bigcirc\\) a) $2.7 \times 10^5$ flowers\
\\(\bigcirc\\) b) $1.8 \times 10^6$ flowers\
\\(\bigcirc\\) c) $2.0 \times 10^6$ flowers\
\\(\bigcirc\\) d) $1.8 \times 10^5$ flowers

Explanation:

Step1: Multiply coefficients

$1.2 \times 1.5 = 1.8$

Step2: Add exponents of 10

$10^2 \times 10^3 = 10^{2+3} = 10^5$

Step3: Combine results

$1.8 \times 10^5$

Answer:

D) $1.8 \times 10^5$ flowers
