Question

1 point If 0.0154 is expressed in the form 1.54 x 10", n is

equal to
1) -2
2) 2
3) 3
4) -3

Answer 1

To express 0.0154 in scientific notation as 1.54 * 10^n, n is equal to -2, since we move the decimal point two places to the right to get from 0.0154 to 1.54.

Step-by-step explanation:

If 0.0154 is expressed in the form 1.54 * 10^n, to determine the value of n, we must move the decimal point in 0.0154 to the right so that the number becomes 1.54.

Since we move the decimal point two places to the right to go from 0.0154 to 1.54, we must use a negative exponent, because moving the decimal point to the right indicates division by a power of 10. Therefore, n is equal to -2, which makes the expression 1.54 x 10^-2.
