I'm assuming that you're asking how to solve equations like this "x2 = y3", right? If you solve for x in equations such as this, you should keep in mind that y will probably have a fractional power or will be the radicand in a radical whose index isn't 2 (in other words, it won't be in a square root). You should also be conscious of the rule for converting radicals to exponents: xa/b equals the b-root of x to the a power.
So, to solve x2 = y3 for x, take the square root of both sides. This results in (x2)1/2 = (y3)1/2. You know that raising a quantity to a power when addition and substraction are absent means that you have to multiply the exponents, so you would then obtain x = y3/2. Using the conversion rule, x equals the square root of y cubed. It is a square root because the denominator of the exponent of y (or "b" if you're looking at the conversion rule) is 2, but things will not always work out so nicely. I hope this helped.
First, subtract 3x from each side of the equation. Then, divide each side of the equation by 7 .
Here are the steps: -- Write the equation. -- Subtract 7 from each side of the equation. -- Subtract 4x from each side. -- Divide each side by 5.
An equation is equal if you have a math problem on each side of an equal sign.
Divide each side of the equation by 10 .
If each side of the equation is a fraction, then it is a proportion.
An exponential equation is one in which a variable occurs in the exponent.An exponential equation in which each side can be expressed interms of the same base can be solved using the property:If the bases are the same, set the exponents equal.
The correct answer is: A reaction that has the same number and type of atoms on each side of the equation.
A "balanced" equation.
1). Add ' 3k ' to each side of the equation. 2). Add ' 5 ' to each side. 3). Divide each side by ' 3 ' .
A balanced equation has equal numbers of each type of atom on each side of the equation.The parts of balanced chemical equation are the reactants on the left side and the products on the right side.
a balanced equation has equal numbers of each type of atom on each side of the equation.
First, subtract 3x from each side of the equation. Then, divide each side of the equation by 7 .
That the number of atoms on the left side of the equation must be the same number of atoms that are on the right side of the equation.
Here are the steps: -- Write the equation. -- Subtract 7 from each side of the equation. -- Subtract 4x from each side. -- Divide each side by 5.
The definition of a balanced chemical equation is one with the same number of atoms on each side of the equation with each molecule electrically neutral. If the reactants and products apparently only switch anions with no extra product such as molecular gas or water, you could end up with an equal number of molecules on each side of the equation.
Divide each side of the equation by 10 .
If each side of the equation is a fraction, then it is a proportion.
