Complete the steps to simplify (y^4/3•y^2/3)^-1/2. Apply the product of powers property to the expression inside the parentheses

MrRissso [65]

Option A

$\left(y^{\frac{4}{3}} \cdot y^{\frac{2}{3}}\right)^{\frac{-1}{2}} = \left(y^{2}\right)^{\frac{-1}{2}}$

Solution:

Given expression is:

$\left(y^{\frac{4}{3}} \cdot y^{\frac{2}{3}}\right)^{\frac{-1}{2}}$

Product of powers property:

The product of powers property tells us that when you multiply powers with the same base you just have to add the exponents

Which is represented as,

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

Therefore, the given expression becomes,

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

Now add the exponents, we get

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

Simplify the above expression

$\left(y^{\frac{6}{3}}\right)^{\frac{-1}{2}}$

Simplify the exponent of y, we get

$\left(y^{2}\right)^{\frac{-1}{2}}$

Thus Option A is correct

azamat

Answer:

$\frac{1}{48}$ th

Step-by-step explanation:

Let X cookies are sold at the local bake sale.

So,

$\frac{X}{4}$ cookies will be made by Kim.

Now,

Given is One-third of her cookies are chocolate chip.

So, One-third of $\frac{X}{4}$ will be chocolate chip

Which is $\frac{X}{12}$ .

Out of whixh one-fourth have nuts.

So, $\frac{X}{48}$ cookies will be having nuts.

So, $\frac{1}{48}$ th of the Total cookies at the bake (X) will be having nuts.

Any nonzero integer divided by 0 equals 0. True or false? Justify your answer.

Vanyuwa [196]

It is false. Although integers above 0 divided by 0 is 0, negative numbers can also be integers (-1,-3,-10, etc.), and when they are divided by zero, they are undefined. That means that it is not really a number.

A ball is thrown into the air at an initial velocity of 18 meters per second from an initial height of 10 meters. The equation t

Sergio039 [100]

Answer:

Step-by-step explanation:

This is your position equation:

$s(t)=-4.9t^2+18t+10$

There's a whole lot of information in that equation, but what we are concerned about right now is the height of the ball after t = 3 seconds. If this is the position of the ball at any time t, we will sub in 3 for t to find out where the ball is at 3 seconds.

$s(3)=-4.9(3^2)+18(3)+10$

which simplifies to

s(3) = -44.1 + 54 + 10 which is

s(3) = 19.9 meters

That's how high the ball is in the air at 3 seconds.

Please Help!!!!!! You have twice as many nickels as pennies. you have $1.10. how many of each coin do you have? Solve each probl

astraxan [27]

There are 20 nickels and 10 pennies.

20 cents x 5 is $1.00 and 10 cents x 1 is 10 cents so it is $1.10 because a nickel is 5 cents so 20x5 is a dollar and a penny is worth 1 cent and 10 pennies is 10 cents so $1.00+$0.10=$1.10 brainliest is appreciated! :)
