Simplify the expression. Assume that all variables are positive. Exponents in simplified form should all be
Rainbow [258]

<u>Given</u>:

The given expression is \frac{7^{\frac{1}{2}} \cdot 7^{\frac{3}{2}}}{7^{-3}}

We need to determine the exponents in simplified form.

<u>Exponents in simplified form:</u>

Let us determine the exponent in simplified form.

Let us apply the exponent rule \frac{x^{a}}{x^{b}}=x^{a-b}

Thus, we have;

7^{\frac{1}{2}+\frac{3}{2}-(-3)}

Adding the fractions, we get;

7^{\frac{4}{2}-(-3)}

Cancelling the common terms, we have;

7^{2-(-3)}

Simplifying the exponent, we get;

7^{2+3}

Adding the exponent, we have;

7^5

Thus, the simplified form of the expression is 7^5

Answer:

A. 6x + 4

B. 22 cm

Step-by-step explanation:

The perimeter of the triangle is equal to the sum of all the side lengths, which is (2x+3) + (x+1) + (3x), or 6x + 4.

When x = 3cm, the perimeter is 6(3) + 4, which is 22 cm.
