The diameter of a plant cell is 8 \cdot 10^{-3} \text { cm}8⋅10 −3 cm8, dot, 10, start superscript, minus, 3, end superscript, start text, space, c, m, end text.

Answer 1

Total diameter of human body cell and plant cell can be given by adding both diameter. Total diameter of human body cell and plant cell  is $8.51\times10^{-3}.$

Given-

Diameter of the human body cell is

$D_h=5.1\times10^{-4}$

Diameter of the plant cell is,

$D_p=8\times10^{-3}$

Total diameter of human body cell and plant cell can be given by adding both diameter. To add or subtract numbers that have exponents you must first make sure that the base and exponent of the two terms you are trying to add or subtract are the same.

Convert the exponents of the plant cell diameter same as the human body cell,

$D_p=8\times10^{-3}$

$D_p=8\times10^{-4+1}$

$D_p=8\times10^{-4}\times 10$

$D_p=80\times10^{-4}$

Total diameter of human body cell and plant cell can be calculated as,

$D_t=D_h+D_p$

$D_t=5.1\times 10^{-4}+80\times 10^{-4}$

$D_t=85.1\times10^{-4}=8.51\times10^{-3}$

Hence, total diameter of human body cell and plant cell  is $8.51\times10^{-3}.$
