Answer 1

Exponents

Initial explanation

We know that an exponent indicates how many times a number is multiplied by itself.

For example

$a^4=a\cdot a\cdot a\cdot a$

When the exponent of a number is 0, the result is always 1:

$a^0=1$

A

In a division of two numbers with the same base, the exponents are substracted:

$\frac{4^8}{4^6}=4^{8-6}=4^2$

Since

4² = 4 · 4 = 16

then

$\frac{4^8}{4^6}=16$

B

Taking into account the intial explanation:

$16^0=1$
