Express the product of 0.0014 and 0.011 in standard form

  • A 1.54 x 10\(^{-2}\)
  • B 1.54 x 10\(^{-3}\)
  • C 1.54 x 10\(^{-4}\)
  • D 1.54 x 10\(^{-5}\)

The correct answer is D. 1.54 x 10\(^{-5}\)

The product of 0.0014 and 0.011 is 0.0000154. 

To express this number in standard form, we need to move the decimal point to the right until it is after the first non-zero digit, which in this case is 1. 

The number of places we need to move the decimal point is the exponent of 10 in the standard form. In this case, we need to move the decimal point 5 places to the right, so the exponent of 10 is -5.

Therefore, the product of 0.0014 and 0.011 expressed in standard form is 1.54 x 10\(^{-5}\).
