Answer 1

Given,

The numbers (1)3,18,65,00,000 (2) 3,90,878 (3) 39087.8 (4) 39087.8.

To Find,

The standard form of those numbers.

Solution,

The standard form of any number can be written a specific format which is A×$10^{x}$ , Where A be can be any number in the range of 1 to 10. And $x$ can be any integer.

Here we will transform all of those into standard form with the method as follows,

The first number is 3,18,65,00,000.

• Assume that the decimal point is just before the end and jump 9 times to the left to obtain the term 3.1865, Which is in between the range 1 to 10.
• So the power of 10 will be 9.
• That means 3,18,65,00,000=3.1865×$10^{9}$.

The second number is 390878.

• Assume that the decimal point is just before the end and jump 5 times to the left to obtain the term 3.90878, Which is in between the range 1 to 10.

• So the power of 10 will be 5.
• That means 390878=3.90878×$10^{5}$.

The third number is 39087.8.

• Assume that the decimal point is just before the end and jump 4 times to the left to obtain the term 3.90878, Which is in between the range 1 to 10.
• So the power of 10 will be 4.
• That means 39087.8=3.90878×$10^{4}$.

The fourth number is also the same as the third.

Hence, We get after converting them is the standard form, (1)3,18,65,00,000=3.1865×$10^{9}$.(2)390878=3.90878×$10^{5}$.(3) 39087.8=3.90878×$10^{4}$.

Answer 2

Answer:

(1) 3,18,65,00,000  $= 3.1865 \times 10^9$

(2) 3,90,878 $= 3.90878 \times 10^5$

(3) 39087.8 $= 3.90878 \times 10^4$

Step-by-step explanation:

The process of writing a given mathematical concept like an equation, number, or expression in certain rules is called the standard form.

Here we will transform all of those into standard form with the method as follows,

(1) 3,18,65,00,000

= 3.1865 × 1000000000

$= 3.1865 \times 10^9$

(2) 3,90,878

= 3.90878 × 100000

$= 3.90878 \times 10^5$

(3) 39087.8

=3.90878 × 10000

$= 3.90878 \times 10^4$
