Which of the following correctly uses exponents to write "6 factors of 2"? A.62 B.26 C.6 ∙ 2 D.12 2m ∙ 2n would be the same as .
A.2m + n B.2m - n C.2mn D.4mn

23^0 is equal to .
A.0 B.1 C.23 D.1/23

Step-by-step explanation:

1. 6 factors of 2 means, 2 multiplied by itself 6 times.  It can be written in the form of exponents as 2⁶.

2.

The law of exponent is :

So,

The correct option is (A).

3. If the power of any number is 0, then the value of that number is equal to 1.

So,

Hence, this is the required solution.

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
