Help me please with This no need to explain

Natalka [10]

Answer:

2.988*10^8

Step-by-step explanation:

to do standard form you have to move the decimal to after the first number so in this case we would move the decimal 8 places from 298800000.0

to 2.98800000 and we can remove the zeros to make it 2.988

then you will plug the times ten and because we move the decimal over 8 it would be 10 to the power of 8 so your answer would be 2.988*10^8

hope this helps have a good day

brainlest please? :)

Step-by-step explanation:

if it is a sample and there are 5 diffrant things that is supposed to be in there, the 5 would be just rediculus, if it is 10, that would make more sense. 40, that would be more like the regular versian of it

Expand (2 + a)9 using Pascal’s triangle.

Natalija [7]

Answer:

Step-by-step explanation:

The Pascal triangle is used to determine the coefficients of the terms when we expand the expression.

1 $(A + B) ^ 0$ = 1

1 1 $(A +B ) ^ 1 = 1A + 1B$

1 2 1 $(A+ B) ^ 2 = 1A^2 + 2 AB + 1B^2$

By extending the triangle, you will get the 9th row, which is your expression, of the coefficients. that is

1 9 36 84 126 126 84 36 9 1

Now, fill in AB in the gaps.

1AB + 9 AB + 36AB + 84AB + 126AB + 126AB +84AB + 36AB + 9AB + 1AB

Next, you need to go from the left to fill out the exponent of A and it will go down from 9 (the exponent of the whole thing) . That is

$1A^9B+9A^8B+36A^7B+84A^6B+126A^5B+126A^4B+84A^3B+36A^2B+9A^1B+1A^0B$

Next will be the exponent of B. this time, you go from the right and do the same with A. You can go from the left also, but go up from 0 to 9 for the exponent of B

$1A^9B^0+9A^8B^1+36A^7B^2+84A^6B^3+126A^5B^4+126A^4B^5+84A^3B^6+36A^2B^7+9A^1B^8+1A^0B^9$
