To multiply factors of 10 (that's anything with zero on the end) just multiply the numbers that are NOT zeros on the end and then add the zeros back onto the answer. For example..
500 × 3
multiply 5 × 3 = 15 then add the 2 zeros back 1,500.
Your problem is 9 × 1000
9 × 1 = 9
add the three zeros back
9,000.
Answer:
There are ways for quickly multiply out a binomial that's being raised by an exponent. Like
(a + b)0 = 1
(a + b)1 = a + b
(a + b)2 = a2 + 2ab + b2
(a + b)3 = (a + b)(a + b)2 = (a + b)(a2 + 2ab + b2) = a3 + 3a2b + 3ab2 + b3
and so on and so on
but there was this mathematician named Blaise Pascal and he found a numerical pattern, called Pascal's Triangle, for quickly expanding a binomial like the ones from earlier. It looks like this
1 1
2 1 2 1
3 1 3 3 1
4 1 4 6 4 1
5 1 5 10 10 5 1
Pascal's Triangle gives us the coefficients for an expanded binomial of the form (a + b)n, where n is the row of the triangle.
Hope this helps!
My best choice is A. -76. I might be wrong! Best of luck. :-)
