Question

(5,5⋅10^​6​​ )⋅(8⋅10^​−7) ​​

Answer 1

(5,5 * 10⁶) * (8*$10^{-7}$) = 5,5 * 10⁶ * 8 * $10^{-7}$ = 44*$10^{-1}$ = 44 * $\frac{1}{10}$ = 22 * $\frac{1}{5}$ = $\frac{22}{5}$

Answer 2

To multiply two numbers written in scientific notation, you can multiply the coefficients (the numbers in front) and add the exponents of 10. Here's how you can do it for your expression:

(5.5 × 10^6) × (8 × 10^(-7))

First, multiply the coefficients (the numbers in front): 5.5 × 8 = 44

Next, add the exponents of 10: 10^6 × 10^(-7) = 10^(6 - 7) = 10^(-1)

Now, combine the coefficient and the exponent of 10: 44 × 10^(-1)

So, (5.5 × 10^6) × (8 × 10^(-7)) = 44 × 10^(-1).

Now, 10^(-1) is the same as 1/10, so:

44 × 10^(-1) = 44 × (1/10) = 4.4

So, the result of the multiplication is 4.4.
