(3*10 to the second power)(1.5*10 the the negative fifth power)

SCIENTIFIC NOTATION: 4.5*10 to the negative third power

My question is what is the standard form I got 4500 but if I look closely at the problem I don't think that's possible please tell me if 4500 is correct

(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.

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).
