Question

Describe how the value of a number written in scientific notation changes when you increase the exponent by 1

Answer 1

The number gets multiplied by 10.

If you have a number written as

`a* 10^k,\quad a \in\mathbb{R},\quad k\in\mathbb{Z}`

If you multiply this number by 10 you get

`a* 10^k* 10 = a*(10^k* 10)=a* 10^(k+1)`
