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

Which procedure justifies whether Negative 3 x (5 minus 4) + 3 (x minus 6) is equivalent to Negative 12 x minus 6? The expressio
Nady [450]

Answer:

The expressions are not equivalent because -3(2)(5-4)+3(2-6)=-18 and -12(2)-6=-30

Step-by-step explanation:

Two expressions are said to be equal if after a number is substituted to the expression, they produce the same result (that is they have the same value).

To determine whether -3x(5-4)+3(x-6) is equivalent to -12x-6, we have to substitute the same number to the expression and see if it produces the same result.

Substituting 2 to the first expression gives:

-3×2(5-4) + 3(2 - 6) = -6 - 12 = -18

Substituting 2 to the second expression gives:

-12(2) - 6 = -24 - 6 = -30

Since -3×2(5-4) + 3(2 - 6) = -6 - 12 = -18 and -12(2) - 6 = -24 - 6 = -30, the expressions are not equivalent because they do not produce the same result.
