How do I write 780,000 in scientific notation.
aniked [119]

the scientific notation is just another mumble jumble way to write the same thing without so many repetitive zeros, so hmmm 780000 has 4 zeros, so what we do is we can say

78 and 4 zeros following it

or we can say

78 * 10⁴, if we get that product, is 780000

in scientific notation, we only leave one digit to the left of the decimal point

so the same thing above can be written as

78 * 10000, can be written as 78.0 * 10000

or as

7.8 * 100000

or as

0.78 * 1000000

check their product

7.8 * 100000, is really just 780000

because we moved the decimal to the left one more slot, it

became 7.8 * 100000

or in

<h2>scientific notation, 7.8 ⨉ 10⁵</h2>

Subtracting with mixed numbers
Troyanec [42]

Answer:

Step-by-step explanation:

Given

\frac{2*2 + 1}{2}    - \frac{2}{3}

= \frac{5}{2} - \frac{2}{3}

Now taking LCM of denominators 2 and 3 we get 6

= \frac{5*3  - 2 * 2}{6}

= \frac{15 - 4}{6}

= \frac{11}{6}

Hope it will help :)
