Question

2*1,6^-19*9*10^4/9,1*10^-31

Answer 1

2 * 1,6⁻¹⁹ * 9 * 10⁴ / (9,1 * 10⁻³¹) скорее всего описка

2 * 1,6 * 10⁻¹⁹ * 9 * 10⁴ / (9,1 * 10⁻³¹)=

2*1,6*9/9,1 * 10⁻¹⁹⁺⁴⁺³¹≈3,16*10¹⁶.

Answer 2

Let's break down the expression step by step:

1. 2 * 1 = 2
2. 6^-19 is a very small number because a negative exponent means taking the reciprocal of the base raised to the positive exponent. So, 6^-19 ≈ 1/(6^19) which is an extremely small number.
3. 9 * 10^4 = 9,000
4. 9.1 * 10^-31 is also a very small number because it has a negative exponent.

Now, let's put it all together:

(2 * 1) * (6^-19 * 9,000) / 9.1 * 10^-31

First, let's simplify the terms:

2 * (1) * (1/(6^19)) * 9,000 / (9.1 * 10^-31)

Now, multiply the numbers:

(2 * 1 * 9,000) / (1/(6^19) * 9.1 * 10^-31)

(18,000) / (1/(6^19) * 9.1 * 10^-31)

Now, divide by the fraction:

18,000 / (1/(6^19) * 9.1 * 10^-31)

To divide by a fraction, you can multiply by its reciprocal:

18,000 * ((6^19) * 9.1 * 10^-31)

Now, calculate the result:

18,000 * (6^19) * 9.1 * 10^-31

This is a very large number because 6^19 is quite large. It would be a very long number to write out, but it's a large positive number.

So, the result is a very large positive number, approximately:

1.05329507 x 10^47 (in scientific notation)
