1. ## scientific notation

Okay I'm having a mental blank. What's 2.240^(x10^-0.3)? Is it 0.002240? lol. Thanks in advance.

2. That's correct. All you have to do is move the decimal point of 2.240 to the left 3 times (because the exponent of 10 is -3).

If the exponent were positive, then move the decimal point to the right.

Do you mean 2.240*[10^(-0.3)]?

If yes, then you cannot solve that mentally, or without a calculator.
Because 10^(-0.3) = 0.50119 in my calculator.
So, 2.24*[10^(-0.3)]
= 2.24*[0.50119]
= 1.12266

4. Yipes! I didn't notice that! My bad...
