CAN SOMEONE HELP ME UNDERSTAND THIS PLEASE
ICE Princess25 [194]

YEAH OFC SHAWTY!

  • so for A its -4^11 because if the powers have the same base and they are being multiplied you add the powers
  • For B its the same idea, they have the same base, and are being multiplied so you add the powers- 13^9
  • For C its similar, you have the same base, but since its Dividing, you subtract the powers. So, 9^5
  • for D you pretend like the denominator has a power of 1 and subtract. So its -24^5-24^1 which hopefully puts it into perspective of being -24^4 becuase we subtracted the powers

I cant do 2 right now, but i will in a minute

<u>And for 3 his mistake is that they arent the same bases so he cant add the powers, he should have converted them to the same base first. </u>
