Remember property of exponents
add exponents of same base
ok so
50,000 is 5 times 10^4
so
50000 times 10^15=
5 times 10^4 times 10^15=
5 times
=
5 times 10^19
Answer:
-2
Step-by-step explanation:
Subtracting a negative number is adding the positive number of that
-3 + 1 += -2
When solving equilibrium problems a quadratic results it has the general form 0 equals x ^ 2 + BX + C a b and c may be positive or negative numbers usually when the wrong answer is plugged in it will lead to a negative concentration or amount. good luck
Just remember that the word "of" means "multiply" in mathematical terms
Now lets get started working out this problem of yours
