Option 3: 2^{\frac{5}{6}} is the right answer

Step-by-step explanation:

Given expression is:

(\sqrt{2})(\sqrt[3]{2} )

In order to simplify the expression we have to convert the radicals in exponents

2^{\frac{1}{2}} . 2^{\frac{1}{3}}

As he base is same, the powers can be added

=2^{\frac{3+2}{6}}\\=2^{\frac{5}{6}}

Hence,

Goshia [24]

ANSWER

15 {x}^{2} + 22x - 5

EXPLANATION

It was given that, the length of the rectangular building is

(3x + 5) \: meters

and the width of the is

(5x - 1) \: meters

The area of a rectangular building is calculated using the formula for finding the area of a rectangle.

A = l \times w

Since the dimensions are given in terms of x, the area is also a function of x,

A(x) = (3x +5 )(5x - 1)

We expand to get,

A(x) = 3x(5x - 1) + 5(5x - 1)

A(x) = 15 {x}^{2}  - 3x + 25x - 5

A(x) = 15 {x}^{2} + 22x - 5
