Which expression is equivalent to 24 Superscript one-third?

Ivahew [28]

Answer:

See explanation

Step-by-step explanation:

The given expression is: $(24)^{\frac{1}{3}}$

Recall that 24=3*8

$\implies(24)^{\frac{1}{3}}=(8*3)^{\frac{1}{3}}$

Recall again that:

$(a*b)^n=a^n*b^n$

$\implies (8*3)^{\frac{1}{3}}=(8)^{\frac{1}{3}}*(3)^{\frac{1}{3}}$

$\implies (8*3)^{\frac{1}{3}}=(2^3)^{\frac{1}{3}}*(3)^{\frac{1}{3}}$

$\implies (8*3)^{\frac{1}{3}}=2^{3*\frac{1}{3}}*(3)^{\frac{1}{3}}$

$\implies (8*3)^{\frac{1}{3}}=2*(3)^{\frac{1}{3}}$

We rewrite in radical form to obtain

$\implies (8*3)^{\frac{1}{3}}=2\sqrt[3]{3}$

Sketch the graph of each equation. y=-2x+1

Allushta [10]

Step-by-step explanation:

y=-2x+1 so we say (-2x+1)

we flip the equation by saying

-2x+1 -1=y+-1

-2x=y-1

Divide both sides by -2

-2÷-1 = y-1÷-2

so x=-1÷2 y=+1÷2
