Since the indices of the roots are the same, we can write the given expression as

fourth root of (400/5), which is "fourth root of 80."

What are some fourth powers?

1^4=1
2^4=16
3^4= 81

Note that 16 is a factor of 80. Therefore:

fourth power of 80 = (fourth power of 16)*(fourth power of 5)
= 2*(fourth power of 5) (answer)

4√400 / 4√ 5 ( both are 'fourth roots ')

= 4√ (400/5)

= 4√80

= 2.99 to nearest hundredth

Answer:

Kamille paid $34.88 for her outfit after tax.

Ms. Roth will pay $59.16 in total.

Step-by-step explanation:

Kamille brought a new outfit that cost $32.00. The tax rate is 9%. How much did she pay for the outfit after tax?

32.00 x 0.09 = 2.88

32 + 2.88 = 34.88

Ms. Roth went to I-Hop for breakfast. She ordered pancakes for $5.00, eggs for $3.50, and orange juice for 42.50. if she tips the waiter 16%, how much will she pay in total?

5 + 3.5 + 42.50 = 51

51 x 0.16 = 8.16

51 + 8.16 = 59.16

Factorize x^2/16+xy+4y^2

lisov135 [29]

Answer:

$\frac{x^2}{16} +xy+4y^2$ can be factored out as: $(\frac{x}{4} +2\,y)^2$

Step-by-step explanation:

Recall the formula for the perfect square of a binomial :

$(a+b)^2=a^2+2ab+b^2$

Now, let's try to identify the values of $a$ and $b$ in the given trinomial.

Notice that the first term and the last term are perfect squares:

$\frac{x^2}{16} = (\frac{x}{4} )^2\\4y^2=(2y)^2$

so, we can investigate what the middle term would be considering our $a=\frac{x}{4}$ , and $b=2y$ :

$2\,a\,b=2\,(\frac{x}{4}) \,(2\,y)=x\,y$

Therefore, the calculated middle term agrees with the given middle term, so we can conclude that this trinomial is the perfect square of the binomial:

$(\frac{x}{4} +2\,y)^2$
