Find the coefficient of the x^3 in the expansion of (2x-9)^5
il63 [147K]

Use the binomial theorem:

\displaystyle (2x-9)^5 = \sum_{k=0}^5 \binom5k (2x)^{5-k}(-9)^k = \sum_{k=0}^5 \frac{5!}{k!(5-k)!} 2^5 \left(-\frac92\right)^k x^{5-k}

The <em>x</em> ³ terms occurs for 5 - <em>k</em> = 3, or <em>k</em> = 2, and its coefficient would be

\dfrac{5!}{2!(5-2)!} 2^5 \left(-\dfrac92\right)^2 = \boxed{6480}

What is the simplified form of 5 square root x^4 • 5 square root x^4
laiz [17]

Answer: C

Step-by-step explanation:

You can write each term into a fraction.

\sqrt[5]{x^4} becomes x^4^/^5

When you multiply 2 terms with the same base, you add the exponents.

x^4^/^5*x^4^/^5=x^4^/^5^+^4^/^5=x^8^/^5

x^8^/^5 is also the same as x\sqrt[5]{x^3}

You get this because \sqrt[5]{x^8} =\sqrt[5]{x*x*x*x*x*x*x*x}. When you pull out 5 os x, you are left with x³ on the inside.
