Answer:

Step-by-step explanation:

√3 (-2+√20) = √3×(-2) + √3×√20

= -2√3 + √3×√(4×5)

= -2√3 + √3×√4×√5

= -2√3 + √3×2×√5

= -2√3 + 2√15

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>
