How does a number in scientific notation change when you multiply it by 100?
solmaris [256]
100 is equal to 10^{2}, So, when you multiply the scientific notation by 100, you should add 2 to the exponent of 10 in that scientific notation:

For example;
9.12* 10^{8} * 100

= 9.12* 10^{8} * 10^{2}

= 9.12* 10^{8+2}

= 9.12* 10^{10}
