Which expression is equivalent to

True [87]

Answer:

$2^{\frac{5}{12}}$

Step-by-step explanation:

The original expression $\sqrt{2^5} ^{\frac{1}{4}}$ can be transformed into $(2^{\frac{5}{3}})^{\frac{1}{4}}$ : both expressions are equivalent, the root of certain number is equivalent to that number power at a fraction whose denominator is the index of the root. The simpliest example for this statement is $\sqrt{x} =x^{\frac{1}{2}}$ (the squared root of x equals x raised at 1/2).
Now, the expression $(2^{\frac{5}{3}})^{\frac{1}{4}}$ can be simplified by using the power of a power property, which simply states that if $b\neq 0$ and $((b)^n)^m=b^{n\times{m}}$ . In this case, then $(2^{\frac{5}{3}})^{\frac{1}{4}}=2^{\frac{5}{3}\times{\frac{1}{4}}}=2^{\frac{5}{12}}$ , which is the final expression.

Amy can paint a room in 12 hours. Alicia can paint the same room in 16 hours. How long does it take for both Amy and Alicia to p

Simora [160]

Well 12 is 3\4 of 16 so honestly it would take the 8 hours working together.

As far as formula if I had to guess it would look like.. 12Amy(Ay)- 16Alicia(Aa) = 4 hours minus 4 from Amy would be 8hours.

in fraction form might make more sense. 3\4 - 4\4 = 1/4 minus that from Amy and she'll finish together with Alicia 4 hours quicker being 8hours.

Step-by-step explanation:

length of side x will be

Tan tita = opp/adjacent

tan65 = x/3

tan 65 is 2.14

so...you are left with 2.14=x/3

by cross multiplying

x= 2.14 × 3

= 6.43

A 9-pound bag of sugar is being split into containers that hold 2/3 of a pound. How many containers will the 9-pound bag create?

Lemur [1.5K]

Answer: below

Step-by-step explanation: You simply need to divide the total amount of sugar (9 lbs) by the amount that you put into each bag (2/3 lb). This expression looks kind of ugly in this form, so let's instead multiply 9 by the reciprocal of 2/3, which in this case is 3/2. The reciprocal of any number is just 1 divided by the number.
