(Note: Exponentiation can be expressed with a carat before the exponent: 3*10^2)
4.5 * 10^-3 (/negative/ third) is .0045.
You've got the sign wrong is all.
Just follow order of operations (exponent, then multiply that product by the other term) to get the others.
can some body help me an algebar
An easier way that I hadn't remembered is to move the decimal point (in 4.5 in this example) to the left (negative) or right (positive) for the value of the exponent (we moved left 3 here).
