I need these numbers in scientific notation, please! Thank you!

Answer 1

`\text{The scientific notation:}\\\\a\cdot10^k\ \text{where}\ 1\leq a<10\ \text{and}\ k\in\mathbb{Z}`

`18.4\ m=1.84\cdot10\ m\\\\0.000000000172\ g=0\underbrace{.0000000001}_(10\to)72=1.72\cdot10^(-10)\ g\\\\4292000\ s=4\underbrace{292000}_(\leftarrow6)\ s=4.292\cdot10^6\ s\\\\8.3\ \cdot10^(-4)\ m\\\\1.496\cdot10^8\ m\\\\23.1\cdot10^(-3)\ kg=2.31\cdot10\cdot10^(-3)\ kg=2.31\cdot10^(-2)\ kg`
