The solution to the polynomial expression since the power of the variable is in the second degree is 6.29 × 10² cm
<h3>What is the power of a variable?</h3>
The power of a variable refers to the exponent of the variable and the highest power of a variable is the degree to which the variable is being raised. From the information given, the highest power of the variable is a polynomial.
Given that:
So, since the exponents are in the same power we are going to add them all together multiplied by their exponent.
i.e.

Answer:
True statement regarding phytoplankton is :
<u>They are the primary photosynthetic plants in the ocean</u>
<u></u>
Explanation:
Phytoplankton : It is made of two words :
"Phyto" means plants
"plankton" means drift .
Hence Phytoplankton are plants that live in water .They are also known as microalgae and are similar to terrestrial plants because they also contain chlorophyll .
Most phytoplanktons are found on the surface of water so that they can get enough sunlight to prepare their food .
There are two kinds of phytoplankton
a) dinoflagellates (they have tail or flagella)
b) diatoms (they are shell like)
<u>They provide food to many organism living in water . example : jelly fish , shrimps etc</u>
<u>Hence they balance the ecosystem</u>
<u>In this way they are primary producers in water -food chain</u>
