You can solve this easily by using Pascal's Triangle (look that up if need be).
Here are the first four rows of P. Triangle:
1
1 1
1 2 1
1 3 3 1
example: expand (a+b)^3.
Look at the 4th row. Borrow and use those coefficients:
1a^3 + 3 a^2b + 3ab^2 + b^3
Now expand (4x+3y)^3:
1(4x)^3 + 3(4x)^2(3y) + 3(4x)*(3y)^2 + (3y)^3
Look at the 2nd term (above):
3(4x)^2(3y) can be re-written as 144x^2y.
The coeff of the 2nd term is 144. Note that (4)^2 = 16
Answer: 5^7
Step-by-step explanation: When multiplying exponents with the same base number you add the exponents together. For example 2^4 x 2^3 will multiply to a product of 2^7.
Answer:
10
Step-by-step explanation:
c^2 = a^2 + b^2
c^2 = 8^2 + 6^2
c^2 = 64 + 36
c^2 = 100
c = 10
