Question

4,27 ×10в7 степени× 4×10 в 4

Answer 1

$4.27 \times 10 {}^{7} \times 4 \times 10 {}^{4} \\ 17.08 \times 10 {}^{11} \\ 1.708 \times 10 {}^{12}$

Answer 2

To multiply numbers in scientific notation, you need to multiply the coefficients (the numbers before the "×10^" part) and add the exponents. Let's calculate:

(4.27 × 10^(-7)) × (4 × 10^4)

Step 1: Multiply the coefficients: 4.27 × 4 = 17.08

Step 2: Add the exponents: 10^(-7) × 10^4 = 10^(4-7) = 10^(-3) (since you subtract the exponents when multiplying with the same base)

Now we have:

17.08 × 10^(-3)

This result can be further simplified. To express it in scientific notation, we want the coefficient to be between 1 and 10. We can do this by moving the decimal point in the coefficient:

17.08 = 1.708 × 10

So, the final result is:

1.708 × 10^(-3)
