Here is code in Python.
#integer value 3 assigned to variable a.
a=3
#integer value 4 assigned to variable v.
b=4
# the value of given expression a * a b *b will be assign to variable c .
c=(a*a)*(b*b)
Explanation:
First an integer value is assigned to variable "a".And then integer 4 is assigned to variable "b". Calculate the value of expression a*ab*b and assigned to variable "c". Here expression a*ab*b can also be written as (a*a)*(b*b).
Answer:
Option B is Correct.
Explanation:
Thermal paste is used in the CPU motherboard to reduce the heat.
Thermal paste is a heat observing coating that is used to make the system cool when it is heated much by working for a long time.
Thermal paste is also used in heat sink in CPU and CPU passes the air in the heat sink to make the temperature normal.
Thermal paste is very useful which installing any processor otherwise which running, the temperature will be increased in the absence of the thermal paste.
It is used to maintain the empty place between the motherboard and the processor.
It will if your not connected to wifi
