Answer:

(-27)^\dfrac{2}{3} = 9

Step-by-step explanation:

Given that,

Asn expression : (-27)^\dfrac{2}{3}

We need to evaluate the above expression.

We know that, (-3)^3=-27

So,

(-27)^\dfrac{2}{3}=(-3)^{3\times \dfrac{2}{3}}

or

=(-3)^2\\\\=-3\times -3\\\\=9

So, the value of (-27)^\dfrac{2}{3} is 9. Hence, the correct option is (b).

A farmer owns about 960 acres of land. If his farm is square, what would be the length of each side in miles, to the nearest ten
OLEGan [10]

It is given in the question that

A farmer owns about 960 acres of land. If his farm is square.

First we convert acres to miles square, and the conversion expression is

1 acre=0.0015625 mi^2

Therefore,

960acres=960*0.0015625=1.5 mi^2

Let the side length of the square be x miles .

And the formula of area of square is

Area=side^2
\\
1.5=side^2
\\
side= \sqrt{1.5}=1.2 miles
