Jed needs to estimate the value of 4.32*10^-4 / 8.71*10^-9 . which statements should he consider? check all that apply. 4.32/8.71 is approximately 2. 4.32/8.71 is approximately 0.5. the answer will be very small because -4-9=-13 . the number will be large because -)=5 he will need to rewrite the preliminary result in scientific notation. the number will be small because the exponent will be a fraction.

Let us first try to simplify (4.32 / 8.71)

On dividing we get 0.49

ON rounding off we get 0.5

So (4.32 / 8.71) is approximately 0.5.

In second part we have to apply property of division of exponents.

applying this for 10⁻⁴ and 10⁻⁹

We have ,

so it becomes 10⁵, the number will be large because -4-(-9)=5.

So the final answer in scientific notation is 0.5 * 10⁵

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844
