How do you simplify (9x^8 y^3)^1/2

kondaur [170]

$\left(9x^8y^3\right)^\frac{1}{2}=\left(3^2x^8y^3\right)^\frac{1}{2}=\left(3^2\right)^\frac{1}{2}\cdot\left(x^8\right)^\frac{1}{2}\cdot\left(y^3\right)^\frac{1}{2}\\\\=3^{2\cdot\frac{1}{2}}\cdot x^{8\cdot\frac{1}{2}}\cdot y^{3\cdot\frac{1}{2}}=3^1\cdot x^4\cdot y^\frac{3}{2}=3x^4\cdot y^{1\frac{1}{2}}\\\\=3x^4\cdot y^{1+\frac{1}{2}}=3x^4\cdot y^1\cdot y^\frac{1}{2}=3x^4y\sqrt{y}$

Write the series -25-22-19 +....for 14 terms using summation notation.

marshall27 [118]

Answer:

$\sum_{n=1}^{14}(3n-28)$

Step-by-step explanation:

The given series is

$-25-22-19+...$

The the first term of the sequence is;

$a_1=-25$

The constant difference is;

$d=-22--25$

$d=3$

The nth term of the series is

$a_n=a_1+d(n-1)$

$a_n=-25+3(n-1)$

$a_n=-25+3n-3$

$a_n=3n-28$

Using the summation notation, we can write the series as;

$\sum_{n=1}^{14}(3n-28)$

2/3x+8/3=2^x<br> WHat is the solution to the equation?<br> x=-2<br> x=-1<br> x=1<br> x=2

Valentin [98]

Pretty sure it's x= -2. multiply everything by 3
then combine.

10= 6^x you can work it like a log and minus 10 from each side.

0= -4^x

so what raised to the power gives you -4? x=-2
