(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

The answer is 1.5×10 to the eighth power

(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).

To multiply numbers in scientific notation, you need to multiply the coefficients and add the exponents.

In this case, we have:

(3 * 10^2) * (1.5 * 10^-5)

First, multiply the coefficients: 3 * 1.5 = 4.5

Next, add the exponents: 10^2 * 10^-5 = 10^(2 + (-5)) = 10^(-3)

So, the answer in scientific notation is 4.5 * 10^-3.

To convert this to standard form, move the decimal point three places to the left, since the exponent is negative. The result is 0.0045.

Therefore, the standard form of the expression (3 * 10^2) * (1.5 * 10^-5) is 0.0045, not 4500.
