First, let's review the formula for the "sum of two cubes:"
a^3 + b^3 = (a + b)(a^2 - ab + b^2).
Unfortunately, 9 is not a perfect cube. The cube root of 9 is 9^(1/3), and the square of the cube root of 9 is therefore 9^(2/3).
Thus,
9x^3 + 64 = (9^(1/3)*x + 4) * (9^(2/3)x^2 - 4*9^(1/3) + 16)
Answer:
2x^2-29 its A
Step-by-step explanation:
5x-5=-25
2x-2=-4
-25+-4=-29
X x X=x^2
X^2 + X^2=2x^2
1. 19/2 is 9 r1
2. 33/4 is 8r1
I hope this helps
<span><span> combine like terms4ln(x) = 8
</span><span>divide both sides by 4.ln(x) = 2
</span><span>exponentiate both sides.<span>eln(x) = e^2</span>
</span><span>inverse property of exponents and logs <span>x = e^<span>2
