Answer:

he added the dimensions of the rectangle. He used the wrong formula. the formula he used was length + breadth. He should have multiplied by 2

6x + 8y +8

Step-by-step explanation:

Perimeter of a rectangle = 2 x (L + B)

L = length

b = breadth

2 (3x + 4y + 4. ) = 6x + 8y +8

Answer:

The equivalent expression \frac{8^4}{7^4} = \frac{4096}{2401}\approx 1.71

Step-by-step explanation:

Given:

(\frac{8}{7})^4

We need to find the equivalent for given expression.

Solution:

(\frac{8}{7})^4

Now by using Law of indices which states;

(\frac{a}{b})^n= \frac{a^n}{b^n}

So applying the same in given expression we get;

\frac{8^4}{7^4}

Now we can say that;

8^4 = 8 \times 8 \times 8 \times 8

Also

7^4 = 7 \times 7 \times 7 \times 7

\frac{8^4}{7^4} = \frac{8 \times 8 \times 8 \times 8}{7 \times 7 \times 7 \times 7}

Now We know that;

8 \times 8 \times 8 \times 8 = 4096

7 \times 7 \times 7 \times 7 = 2401

On substituting we get;

\frac{8^4}{7^4} = \frac{4096}{2401}\approx 1.71

Hence The equivalent expression \frac{8^4}{7^4} = \frac{4096}{2401}\approx 1.71
