Question

Simplify the expression x5 • x7.

Answer 1

Answer:

x^12

Step-by-step 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

Answer:

x12

Step-by-step 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)
