Step-by-step explanation:
4×10×2=80
20×10×1=200
20×8×1=160
20×10×1=200
2×20×1=40
10×2×2=40
80+200+160+200+40+40=720
 
        
             
        
        
        
Given:
Size of a red blood cell = 0.000007 m
Size of a plant cell = 0.0000127 m
To find:
The comparison of these two values.
Solution:
We have,
Size of a red blood cell = 0.000007 m
Size of a plant cell = 0.0000127 m
Clearly,  . Now, the difference between these two values is:
. Now, the difference between these two values is:

Therefore, the size of a plant cell is 0.0000057 m more than the size of a red blood cell.
 
        
             
        
        
        
Answer:
- 1/4 
Step-by-step explanation:
Where you see X, substitute with 1/3
Solve the power/exponent first:
6(1/3) = 2
That is ; - 4(1/4)^2
Solve the parenthesis: 
(1/4)^2 = 1/16
-4(1/16)
= - 1/4
