Write 4.5x10^-1 in standard (normal) notation:

• 4.5

• 0.45

• 0.045

• 45

If you write 0.43 x 10^-3 in scientific notation, the exponent will get more negative or less negative?

• More negative because 0.43 is less than 1 so it alone will have a - exponent. When you combine two - exponents, they get more negative.

• More negative. When you change 0.43 to 4.3, the new number is "bigger", so the 10^x value you multiply by must have a "smaller" value in order for the two numbers to be equivalent.

• More positive. When you change 0.43 to 4.3, the number is getting bigger, so you have to make the second number bigger too for them to be equivalent.

• More positive because 0.43 is less than 1 so it will have a positive exponent.
