Question

Simplify the expression x5 • x7.

Answer 1

x^12

Explanation:

When multiplying exponents, the rule below is followed.

`x^a * x^b= x^(a+b)`

Basically, the base remains the same, but the numbers in the exponents are added.

We are given:

`x^5*x^7`

We leave the base (x)as is, and add the numbers in the exponents (5 and 7).

`x^5*x^7\\`

`x^{5+7`

`x^(12)`

The expression
`x^5*x^7\\` can be simplified as:
`x^{12{`

Answer 2

x12

Explanation:

When multipling numbers that are the same with exponent you can just add the exponents.

so x5*x7=x12

(It would be subtraction if there was division)
