You expand the parenthesis out first. Then simplify the rest.
Parenthesis
Yes, and parenthesis are the first thing you solve.
You square the number in the parentheses.
What I mean by this equation is: x^3-2x^(x-2.5)+x^(x^x)
Use the quadratic formula for the equality. Then, depending on the coefficient of x2 and the nature of the inequality [>, ≥, ≤, <], determine whether you need the open or closed intervals between the roots or beyond the roots.
It depends on which compound interest formula you mean. Refer to the Wikipedia Article on "Compound Interest" for the correct terminology.
You should solve for an empirical formula when you are given the percent composition of elements in a compound or when you have the molar mass of the compound but not the molecular formula. The empirical formula provides the simplest whole-number ratio of atoms in a compound.
Parenthesis
Yes, and parenthesis are the first thing you solve.
This is not an inequality. There is no <,>, or = sign.
Solve the inequality and enter your solution as an inequality comparing the variable to the solution. -33+x<-33
To solve for the formula mass of a compound, add the atomic masses of all the elements in the formula, using the periodic table to find each element's atomic mass. For percentage composition, divide the total mass of each element in the formula by the formula mass of the compound, then multiply by 100 to convert it to a percentage. This provides the contribution of each element to the overall mass of the compound.
Parentheses is when you are doing an equation, and you solve the problem.
There is no equation not inequality. So there is nothing to solve!
7a=2(-10)........................................answer is 20/7
The above is not an inequality as stated.
