Hi! Algebra two question, rational exponents.

ivanzaharov [21]

Simplifying $\left(x^2+8xy+16y^2\right)^{\frac{1}{3}}.\left(x+4y\right)^{\frac{1}{3}}$ we get $\left(x+4y\right)}$

Step-by-step explanation:

We need to simplify:

$\left(x^2+8xy+16y^2\right)^{\frac{1}{3}}.\left(x+4y\right)^{\frac{1}{3}}$

For solving, we will first simplify the terms inside the exponent and then solve exponent

First Solving: $\left(x^2+8xy+16y^2\right)}.\left(x+4y\right)}$

Using the formula: $(a^2+2ab+b^2)=(a+b)^2$

$\left(x^2+8xy+16y^2\right)}.\left(x+4y\right)}\\\left((x)^2+2(x)(4y)+(4y)^2\right)}.\left(x+4y\right)}\\\left(x+4y\right)^2}.\left(x+4y\right)}$

Using exponent rule:

$a^m.a^n=a^{m+n}$

$\left(x+4y\right)^{2+1}}\\\left(x+4y\right)^3}$

Now,

$(\left(x+4y\right)^3})^{\frac{1}{3}}\\Simplifiying:\\\left(x+4y\right)}^{\frac{3}{3}}\\\left(x+4y\right)}$

So, simplifying $\left(x^2+8xy+16y^2\right)^{\frac{1}{3}}.\left(x+4y\right)^{\frac{1}{3}}$ we get $\left(x+4y\right)}$

i left home going to the movies. i had $90 when i left the house. i spent 31/45 on tickets, and out of the remaining cash i spen

ad-work [718]

First you can find $\frac{31}{45}$ of 90.

90 x $\frac{31}{45}$ = 62

Next, you have $62 left and spent $\frac{1}{7}$ of it. Meaning you have $\frac{6}{7}$ of 62 left.

62 x $\frac{6}{7}$ = about <span>53.14285

As your answer is not a whole number, you could round according to whatever guidelines your homework has given you (for example - rounding to the 2nd decimal place $53.14)

Find the product of the complex numbers

lukranit [14]

Answer:

17.32 + 10i

Step-by-step explanation:

The product of the complex numbers;

z, = 5( cos 20° + i sin 20°)

za = 4( cos 10° + i sin 10°)

5( cos 20° + i sin 20°) × 4( cos 10° + i sin 10°)

= 20(cos20(cos10) + i sin20(cos10) + i sin10(cos20) + isin20(i sin10))

= 20(cos20(cos10) + i sin20(cos10) + i sin10(cos20) + sin20(sin10)i^2 )

And i^2 = -1

= 20(cos20(cos10) + i sin20(cos10) + i sin10(cos20) - sin20(sin10) )

= 20(cos20(cos10) - sin20(sin10) + i(sin20(cos10) + sin10(cos20)))

= 20(0.866 + i(0.5))

= 17.32 + 10i
