Question

1.98 x 10⁻⁴ / 1.72 x 10⁻⁶ =

Answer 1

To calculate 1.98 x 10⁻⁴ / 1.72 x 10⁻⁶, divide the coefficients and subtract the exponents. The result is 1.151 x 10², or 115.1 in decimal form.

Step-by-step explanation:

The question involves the division of two numbers expressed in scientific notation. To solve for 1.98 x 10⁻⁴ / 1.72 x 10⁻⁶, first divide the coefficients (1.98/1.72) to get approximately 1.151. Next, subtract the exponents of 10 (-4 - (-6)) to get +2. Combining the results, we have 1.151 x 10², which is the coefficient multiplied by 10 raised to the power obtained from subtracting the exponents.

The final answer in scientific notation is 1.151 x 10², which can be read as 115.1 when expressed in standard decimal form.
