Scientific Notation:<br> what’s (2.2 x 10 to the -4) - (3 x 10 to the 2)

Marrrta [24]

Answer:

$2.23\times10^4$

Step-by-step explanation:

In order to get the answer to this question you need to turn the scientific notations into standard form then subtract the two standard forms.

$(2.2\times10^{-4})-(3\times10^2)$

Turn the notations into standard form:

$2.2\times10^{-4} = .00022$

$3\times10^2=300$

$.00022-300=22300$

$=22300$

Turn into notation form:

$22300 = 2.23\times10^{4}$

Hope this helps.

(4+5)-2 thxs for answering!!!!!!!!!!!!!!

Arisa [49]

Answer: 7

Step-by-step explanation:

$(4+5)-2$

You can either remove brackets and just do a little addition and subtraction.

$4+5-2$

$9-2\\7$

So the answer is 7.

Or just finish things inside the brackets first.

$(4+5)-2\\9-2\\7$

So the answer is 7.

___H2 + ___Br2 → ___HBr

Vaselesa [24]

Answer:H2+Br2-->2HBr

Step-by-step explanation:

The amount of atoms on the left side must be equal to the amount of atoms on the right side for each element.

On the left you got 2xH and 2xBr.

This means you must have the same amount on the right.

2HBr =2xH + 2xBr
