486 = 18 * 3 * w

w = 486 / (18*3)

= 486 / 54

Simplify. Express the answers using positive exponents:

olasank [31]

Answer:

$\frac{-1}{2}ab^{12}$

$\frac{w^{10}}{3y^4}$

Step-by-step explanation:

Given the expression;

$\frac{-2a^2b^4}{4ab^{-8}}\\= \frac{-2}{4}*a^{2-1}b^{4-(-8)}\\= \frac{-1}{2}ab^{12}$

Similarly for the expression;

$\frac{-5w^4y^{-2}}{-15w^{-6}y^2}\\= \frac{-5}{-15}*w^{4-(-6)}y^{-2-2}\\= \frac{1}{3}w^{10}y^{-4} \\= \frac{w^{10}}{3y^4}$

Which two values of x are roots of the polynomial below?<br> 5x2 - 5x+1

Natalija [7]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

$5 {x}^{2} - 5x + 1 = 0$

$(x - \frac{5 + \sqrt{5} }{10} )(x - \frac{5 - \sqrt{5} }{10} ) = 0 \\$

Thus :

$x = \frac{5 + \sqrt{5} }{10} \\$

$x = \frac{5 - \sqrt{5} }{10} \\$

Answer:

Step-by-step explanation:

4^2 +5*3^2 -4^2 / 2^3

order of operations says to do first parenthesis, exponents, then division and multiplication

first the exponents

4^2 = 16

3^2= 9

4^2=16

2^3=8

16+ 5*9-16/8

then multiply 5*9

=16+ 45 -16/8

simplify the fraction

=16+ 45 -2
