Question

Considerate of these three numbers express and scientific notation 8.2×10 to the -3rd power 5.2×10 to the $96 and 4.1 times since I'm -6 hours which number is the greatest invite how many times does it rather than smallest number

Answer 1

`8.2 * 10^(-3)` is the greatest

2000 times greater

Explanation:

Given

`8.2 * 10^(-3)`

`5.2 * 10^(-6)`

`4.1 * 10^(-6)`

Solving (a): The greatest of the numbers

First, we convert them to decimals:

`8.2 * 10^(-3) = 0.0082`

`5.2 * 10^(-6) = 0.0000052`

`4.1 * 10^(-6) = 0.0000041`

By comparing the decimal numbers, the highest is: 0.0082.

Hence,

`8.2 * 10^(-3)` is the greatest

Solving (b): How many times greater than the smallest

In (a) above:

The greatest is:
`8.2 * 10^(-3)`

By comparing the decimal numbers,

The smallest is: 0.0000041 i.e.
`4.1 * 10^(-6)`

The number of times the greatest is greater than the smallest is:

`Number = (8.2 * 10^(-3))/(4.1 * 10^(-6))`

`Number = (0.0082)/(0.0000041)`

`Number = 2000`

Hence, it is 2000 times greater
