the unknowns must be the same variable and the exponents have to be the same.
examples)
x4 + y4 cannot be added because they are not the same variable.
x3 + x2 cannot be added because they have different exponents.
3y6 + 5y6 can be added because they have the same variable and exponents.
(answer: 8y6)

What is the exponential form of 2x2x2x2x5?

When multiplying a number with exponents do you add or multiply the exponents?
You add exponents when multiplying. Ex: (xm) × (xn) = xm+n
When subtracting variables with exponents do you add or subtract the exponenets?
You cannot ad or subtract variables with different exponents: the exponents must be the same. The coefficients are added or subtracted and the exponent of the answer is the common exponent. (The rules are similar to those for the denominators of fractions.)Thus 2x^2 + 5x^3 cannot be combined into a single term.while 2x^2 + 5x^2 = (2+5)*x^2 = 7x^2
What you do with the exponents when you you are multiplying?
If you are multiplying numbers with exponents, and the base is the same, you can just add exponents. For example, 104 x 105 = 109.
How do you solve multiplication with like terms?
Just multiply the coefficients, leave the variable the same, and add the exponents.

What is r4 squared times 3r squared?
Do you mean? 4r2 * 3r2 = 12r4 ====== You multiply the coefficients of the variable terms and add the exponents.
What is x2 multiplied by 2x?
X2 * 2X= 2X3======multiply coefficients and add exponents ( all variables have a 1 as implied exponent )
What does 9y to the 4th power times y to the fifth power equals to?
9Y^4 * Y^5 add exponents and coefficients multiplied 9Y^9
When adding numbers with exponents do you add or subtract the exponents?
you do not do anything when you add numbers with exponents. you just figure out the answer. it is only if you multiply numbers with exponents, where you add the exponents..
What are the common characteristic between simultaneous linear equations in 2 unknowns which have no solutions?
The coefficients and constant in one of the equations are a multiple of the corresponding coefficients and constant in the other equation.
When you are multiplying exponents do you only add the exponents or do you also multiply the bases?
Add the exponents
When multiplying binomials that turn out negative do you add or subtract exponents?
When multiplying numbers with exponents, you add the exponents.
