Question

The weight of a honeybee is 1.2\cdot10^{-1}\text{ g}1.2⋅10 −1 g1, point, 2, dot, 10, start superscript, minus, 1, end superscript, start text, space, g, end text. The weight of the pollen collected by the bee on one trip is 6.0 \cdot 10^{-2} \text{ g}6.0⋅10 −2 g6, point, 0, dot, 10, start superscript, minus, 2, end superscript, start text, space, g, end text. What is the combined weight of the bee and the pollen? Express your answer in scientific notation.

Answer 1

1.8 x 10^-1

Explanation:

it would be 0.18 withought scientific notation.

Answer 2

0.18 g

Explanation:

Weight of honeybee =
`1.2* 10^(-1)\ \text{g}`

Weight of pollen =
`6* 10^(-2)\ \text{g}`

The above values can be written in the following ways

`1.2* 10^(-1)\ \text{g}=0.12\ \text{g}`

`6* 10^(-2)\ \text{g}=0.06\ \text{g}`

Weight mass =
`0.12+0.06=0.18\ \text{g}`

The combined weight of the honeybee and the pollen is 0.18 g.
