What is the expression in radical form?

Mathematics
1 answer:
BabaBlast [244]3 years ago
3 0

Answer:

32x^9y^6/5

Step-by-step explanation:

Factor (4x^3y^2)^3 and get 2^6(x^3)^3(y^2)^3

Factor 10: 2 x 5

Then get 2^6(x^3)^3(y^2)^3/2 x 5

Cancel the common factor, 2

2^5(x^3)^3(y^2)^3/5

(x^3)^3=x^9

2^5x^9(y^2)^3/5

(y^2)^3=y^6

2^5x^9y^6/5

2^5=32

32x^9y^6/5

Help Please<br> A) estimate 49 of 162. <br> B) use mental math to calculate 49 of 162
bija089 [108]
You can round 49 to 50 and you can round 162 to 200.

You know that 5 * 2 = 10, so 50 * 200 must be 1000. You just add the zeroes.

I finished question 1 but I could use some help on the others​
Eddi Din [679]

Answer:

With the first four questions, all you need to do is find a value of x that gives you a zero value in any one of those brackets.  Let's do it.

You said you finished 1, so let's skip it.

I can't give you a full answer for question 2, because you didn't capture the entire expression in the screenshot.  I can see that the values 3 and 0.125 would give zero values, but I can't tell you the last.

For question three, we need to find x values where either 9x + 3 = 0, or x² - 9 = 0.  There are three values that meet those conditions.  You can solve it just by assigning a zero value and solving for x:

9x + 3 = 0\\3x + 1 = 0\\3x = -1\\x = -1/3

For the second term actually has two solutions, because a squaring a number also causes negatives to be converted to positives.  Another way of seeing this is to notice that the second term is actually a difference of squares:

p(x) = (9x + 3)(x^2 - 9)\\= (9x + 3)(x + 3)(x - 3)

so in this case x could be -1/3, -3, or 3 to give a zero value.

For question four, you can only get a zero if you use imaginary numbers, as no real number can be squared to give you a negative.  So the only answers to that are 5i, or -5i.

With questions five six seven and eight, we just need to make exceptions for zero denominators, so:

For question 5, you can x can be any real number except -4, 2 and 7

For 6, x can be anything but 3, 1/8th or 5

for 7, We again have that difference of squares, so the actual denominator is (9x + 3)(x + 9)(x - 9), meaning x can be anything but -1/3, -9, or 9

And finally for question 8, we again have a squaring, meaning that only an imaginary number will cause division by zero, meaning x can't be 5i or -5i.

Lobsters Each year, 183 million pounds of lobster are caught in
oee [108]

Answer:

The quantity of lobster which are sold live each year in the United States and  Canada are 46 million pounds (approximately).

Step-by-step explanation:

Given:

Each year, 183 million pounds of lobster are caught in  the United States and Canada. Twenty-five percent of this amount is  sold live.

Now, to find how  many pounds of lobster are sold live each year in the United States and  Canada.

According to question:

25% of 183 million pounds.

\frac{25}{100}\times 183

=0.25\times 183

=45.75

<em>Each year 45.75 million pounds of lobster are sold live in the United States and Canada.</em>

Therefore, the quantity of lobster which are sold live each year in the United States and  Canada are 46 million pounds (approximately).
