Answer 2

Concept

Standard form of a number is a method of writing a number in the form that follows certain rules.

Any number which can be written as a decimal number, between 1.0 and 10.0, multiplied by a power of 10 is said to in standard form.

Given

1) 3430,000

2) 70,040,000,000

3) 0.00000015

4) 0.00001436

Find

Express the numbers in the standard form

Solution

So here we need to show the numbers in the power of 10 which is the standard form of the numbers.

1) 3430,000

= 3.43 * 1000000

=3.43 * 10^6

2) 70,040,000,000

= 7.04 * 10000000000

= 7.04 * 10^10

3) 0.00000015

= 1.5 * 10^-7

4) 0.00001436

= 1436 * 10^-5

1) 3430,000 = 3.43 * 10^6

2) 70,040,000,000 = 7.04 * 10^10

3) 0.00000015 = 1.5 * 10^-7

4) 0.00001436 = 1436 * 10^-5
