Answer:

Step-by-step explanation:

Length = x+3

Width = x-1

Area = l*b

where l is the length of the bedroom

and b is the breadth or width of the bedroom

The polynomial can be written as:

Area=(x+3)(x-1)

Now we will find the area of the room when x=10

First we will find the values of length and width.

Length = x+3

Length = 10+3 = 13

Width = x-1

Width = 10-1=9

Now put the values in the formula:

Area=l*b

Area=13*9

Area = 117 square feet....

Why is 3^7 equal to 7 1/3
valentinak56 [21]

The required answer is (7^{\frac{1}{3}})^{3} = (7^{\frac{1}{3}*3}) = 7^1=7.

<u>what is a power rule for exponents ?</u>

(a^m)^n=a^{mn} is known as the power rule for exponents. Exponent times power is how you raise a number with an exponent to a power.

A number's exponent demonstrates how many times we are multiplying a given number by itself. 3^4, for instance, indicates that we are multiplying 3 by four. 3*3*3*3 is its expanded form. The power of a number is another name for an exponent. It could be an integer, a fraction, a negative integer, or a decimal.

(7^{\frac{1}{3}})^{3} = (7^{\frac{1}{3}*3}) = 7^1=7

Here, we have used the rule (a^m)^n=a^{mn}
