Jill, Meg and Beth are sister's. Jill is 2 years younger than Meg. Beth is half as old as Meg. Let m represent Meg's age. Write

pshichka [43]

Answer:

Two other algebraic expressions based on this situation are:

$J = m-2$

$B = \frac{m}{2}$

Step-by-step explanation:

Let m represent Meg's age.

Jill is 2 years younger than Meg.

Let J represents Jill's age

Jill's age $J = m-2$

Beth is half as old as Meg

Let B represents Beth's age

Beth's age $B = \frac{m}{2}$

So, two other algebraic expressions based on this situation are:

$J = m-2$

$B = \frac{m}{2}$

Rewrite in simplest radical form square root of x times the fourth root of x. Show each step of your process.

Ipatiy [6.2K]

Answer:

$\sqrt[4] {x^3}$

Step-by-step explanation:

At this point, we can transform the square root into a fourth root by squaring the argument, and bring into the other root:

$\sqrt x \cdot \sqrt[4] x =\sqrt [4] {x^2} \cdot \sqrt[4] x = \sqrt[4]{x^2\cdot x} = \sqrt[4] {x^3}$

Alternatively, if you're allowed to use rational exponents, we can convert everything:

$\sqrt x \cdot \sqrt[4] x = x^{\frac12} \cdot x^\frac14 = x^{\frac12 +\frac14}= x^{\frac24 +\frac14}= x^\frac34 = \sqrt[4] {x^3}$
