When multiplying exponents, such as x times x, would the answer be x squared or 2x?

Question

Thanks so much!!!!!

Answer 1

"X times X" equals X squared.

2X is the same as saying "X + X".

If in doubt, substitute a number for the exponent in question (just not 0, 1, or 2). Three works very nicely. For example: 3 times 3 = 9, but 2(3)=6.

Answer 2

The answer would be x^2 because when multiplying exponents you are adding them. Remember the rules of exponents. When you multiply exponents you will be adding them and when you divide exponents you will be subtracting them. For example, in the example that you use with x times x what you are really doing is adding the ones that are implied with the x ( In other words when you have a variable such as x it is x^1, the one is automatically implied). Since the variables are the same the x remains the same and when added the exponents equal 2 so your answer would be x^2. Now if the equation was x + x, then your answer WOULD BE 2x. But because it is multiplication, you are simply adding the numbers that are with the variable. Another example to help you understand what I'm saying would be this, (x^2)(x^2) = x^4
(x^3)(x^3) = x^6, etc. And if you were dividing exponents, you could have something like this

(x^2)/(x^4) = 1/x^2 because the x^2 would cancel out with two of the x's on the bottom leaving only an x^2. Rember when multiplying exponents you will add and when dividing exponents you will subtract.

Answer 3

x squared. 2x just means two times that number. A number squared means that number times that number. X is a variable in this case.

If x is an exponent, to multiply exponents you add them together. 2^4 x 3^6 = 6^10

Answer 4

the answer would be x squared. if you were adding the x's the answer would be 2x. when multiplying variables, add the exponents together, in this case x^1 times x^1 equals x^2. when adding variables, add the coeficients, or 1x plus 1x equals 2x
(note: x^2 means "x to the power of 2" or x squared)
a more complicated example would be:
x^3 time x^7 equals x^10
and
3x plus 7x equals 10x

Answer 5

while multiplying exponents, you will might desire to characteristic them. occasion x^7 * x^4 = x^11 while raising an exponential expression to a chosen energy, you ought to multiply the exponents occasion (x^7)^4 = x^28 while dividing exponents, you subtract them. (x^7)/(x^4) = x^3 that's purely like the multiplication rule on condition that a million/x^4 is comparable to x^(-4) so which you will rewrite it as x^7 * x^-4 and then upload them to get x^3 as quickly as extra. the respond on your probem is x^6 * y^9

Answer 6

x squared. When multiplying like exponents. Add the exponents. When multiplying inside a quantity then you will multiply the exponents subscripts

Answer 7

its X squared. 2 times x makes 2x not x squared.

Answer 8

if you are multipliing numbers with exponents like 2^3x3^5, then you muliply the regular numbers and just add the exponents together. (6^8)

Answer 9

x squared. It would be like multiplying 9x9 as opposed to 2 x 9.

Answer 10

your question does not make sense. you are not multiplying exponents in your example however x times x is x squared x+x=2x
