1:1 = "1 to 1"

1*1 = "1 times 1" or "1 multiplied by 1"

2*10^5 = "2 times 10 to the fifth power" or "2 times 10 raised to the fifth power"

2*10^-5 = "2 times 10 to the negative fifth power" or "2 times 10 raised to the negative fifth power"


Extra:
2^1 = "2 to the first power"
2^2 = "2 squared"
2^3 = "2 cubed"
2^4 = "2 to the forth power"
2^5 = "2 to the fifth power"


2/2 = "two divided by two"
2! = two factorial

thanks for telling us such kind of useful expressions

in canada, we usually read them like this:

2*10^5 = "two times ten to the power of five" or "two times ten fifth power"

2*10^-5 = "two times ten to the power of negative five" or "two times ten negative fifth power"

in some cases, we just omit the power. for example: 2*10^5 = "two times ten fifth"

2/2 = "two over two"
2/3 = "two over three"
