Answer:
1.08×10^11
Step-by-step explanation:
1.08 times 10 to the power of 11
The number of pieces of mail in 1995 more than 1965 by = 1.08 * [tex]10^{11}[/tex]
Exponent refers to the number of times a number is used in a multiplication. Power can be defined as a number being multiplied by itself a specific number of times. Exponent is the number to which a number is raised so as to define its power as a whole expression.
In 1995 : 1.8 * [tex]10^{11 }[/tex]
In 1965: 7.2 * [tex]10^{10 }[/tex]
So, the difference will be
= 1.8 * [tex]10^{11 }[/tex] - 7.2 * [tex]10^{10 }[/tex]
= 1.8 * [tex]10^{10}*10[/tex] - 7.2 * [tex]10^{10 }[/tex]
=18 * [tex]10^{10 }[/tex] - 7.2 * [tex]10^{10 }[/tex]
= (18-7.2) * [tex]10^{10 }[/tex]
=10.8 * [tex]10^{10 }[/tex]
= 1.08 * [tex]10^{11}[/tex]
Hence, the number of pieces of mail in 1995 more than 1965 by = 1.08 * [tex]10^{11}[/tex]
