Which of the following is less than 6.5 × 10–5.
A. 1.4 × 10–3
B. 2.5 × 10–4
C. 7.8 × 10–5
D. 4.6 × 10–6
No, James, nothing you wrote makes sense.
Here are the multiple choice answers.
A. 1.4 × 10–3
B. 2.5 × 10–4
C. 7.8 × 10–5
D. 4.6 × 10–6
Change each of the answers without the exponents; i.e.,
0.0014
0.00025
0.000078
0.000065--you want the number smaller than this.
0.0000046
It is easily seen the number smaller than 6.5 x 10-5
multiply the problem in the question and then multiply the answers and the one that is less than the one In the problem then that is your answer does that make sense if not let me know and I will give you an example
if it is muipltle choice then pick d,c,b,a and if not then you can pick one of them answers
To determine which of the given options is less than 6.5 × 10–5, you need to compare the values of the options with 6.5 × 10–5.
Let's compare each option:
A. 1.4 × 10–3: To compare this value, you need to convert it to scientific notation with the same exponent as 6.5 × 10–5. Converting 1.4 × 10–3 to the same exponent gives 1.4 × 10–5. Since 1.4 × 10–5 is greater than 6.5 × 10–5, option A is not less.
B. 2.5 × 10–4: By converting 2.5 × 10–4 to the same exponent as 6.5 × 10–5, you get 2.5 × 10–5. Since 2.5 × 10–5 is greater than 6.5 × 10–5, option B is also not less.
C. 7.8 × 10–5: This option already has the same exponent as 6.5 × 10–5. Now you can compare the coefficients of the two values. Since 7.8 is greater than 6.5, option C is not less.
D. 4.6 × 10–6: Once again, convert this option to the same exponent as 6.5 × 10–5. Converting 4.6 × 10–6 gives 4.6 × 10–5. Since 4.6 × 10–5 is less than 6.5 × 10–5, option D is less.
Therefore, the option that is less than 6.5 × 10–5 is D. 4.6 × 10–6.
