Question

How many times greater is 4.65 X 10% than 7.5 x 10? Express your answer using either standard notation or scientific notation.

Answer 1

Given:

`4.65*10^8\text{ and }7.5*10^6.`

Aim:

`\text{ We need to find the number of times greater is }4.65*10^8\text{ than }7.5*10^6.`

Step-by-step explanation:

`\text{ Divide }4.65*10^8\text{ by }7.5*10^6to\text{ find the number of times greater.}`
`(4.65*10^8)/(7.5*10^6)=(4.65*100000000)/(7.5*1000000)`

`=(465000000)/(7500000)`

`=(4650)/(75)`
`=62`

Multiply and divide by 10 to get the scientific notation.​

`=62*(10)/(10)`

`=6.2*10`

Final answer:

`6.2*10^1`
