Question

the weight of a honeybee is 1.2·10⁻¹ g. the weight of the pollen collected by the bee on one trip is 6.0·10⁻² g. what is the combined weight of the bee and the pollen? express your answer in scientific notation.

Explanation:

Step1: Identify the weights

The weight of the honey - bee is $1.2\times10^{-1}$ g and the weight of the pollen is $6.0\times10^{-2}$ g.

Step2: Make the exponents the same

Rewrite $1.2\times10^{-1}$ as $12\times10^{-2}$.

Step3: Add the weights

$(12\times10^{-2})+(6.0\times10^{-2})=(12 + 6.0)\times10^{-2}=18\times10^{-2}$

Step4: Convert to proper scientific notation

$18\times10^{-2}=1.8\times10^{-1}$ g

Answer:

$1.8\times10^{-1}$ g
