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..

If you are adding or subtracting two numbers in scientific notation the exponents must be the same before adding the coefficients. This is similar to 'like terms' in algebraic expressions. You can't add 5x3 and 3x2 because the exponents are not the same.

in adding scientific notations you have to make their exponents the same then add the numbers. after you add coppy th x 10 and its exponent ex. 1.25 x 10e10 + 7.5 x 10e9 =1.25 x 10e10 + 0.75 x10e10(you can see that the decimal point is move to the left so that its exponent will be equal) =2.0 x 10e10(final ans.)

Write the prime factorization with exponents. Add 1 to each exponent. (Numbers without exponents actually have the exponent 1.) Multiply them together. That will be the number of factors. 10 = 2 x 5 = 21 x 51 2 x 2 = 4 10 has four factors. 72 = 23 x 32 4 x 3 = 12 72 has twelve factors. Square numbers can be tricky. The prime factorization of 9 should be written as 32, not 3 x 3. Adding 1 to the 2 gives you 3. 9 has three factors.

To simplify, you write one copy of the base, then add the exponent. Example:x^5 times x^3 = x^8 In the case of positive integer exponents, this can easily be derived by writing each power as a repeated multiplication. However, this law is also valid for negative or fractional exponents.

when you add mixed numbers you have a whole number but adding fraction does not.

just add the numbers

When multiplying numbers with exponents, you add the exponents.

When multiplying something with exponents, you add it. When dividing something with exponents, you subtract it.

nothing, keep the exponents the same, remember you can only add or subtract when the exponents are the same

If the base numbers or variables are the same, you add the exponents.

The answer depends on what you wish to achieve.

You should multiply the numbers, but add the exponents. For example: 92 x 27 = 189

add them

If you are multiplying numbers with exponents, and the base is the same, you can just add exponents. For example, 104 x 105 = 109.

That depends on what you are adding it to.
