Question

Does anyone know??

i need help like really bad

Answer 1

Down below :#

Explanation:

The first one is False: reason
`\mathrm{Apply\:exponent\:rule}:\quad \:a^b\cdot \:a^c=a^(b+c)`

`b^9b^2=b^(9+2)`

`=b^(9+2)`

And then its b^11

Second one is false

Third one is True

Fourth false

Reason:
`\mathrm{Apply\:exponent\:rule:\:}\left(a^b\right)^c=a^(bc),\:\quad \mathrm{\:assuming\:}a\ge 0`

`=b^(6\cdot \:5)`

fifth one is False

`\mathrm{Apply\:exponent\:rule:\:}a^0=1,\:\quad \mathrm{\:assuming\:}a\\e \:0`

That equals 1

:) hope this helps
