Answer:

(a)\ \frac{6^7}{6^4} = \frac{6*6*6*6*6*6*6}{6*6*6*6} --- expanded form

(b)\ \frac{6^7}{6^4} = 6*6*6 --- Divide common factor

(c) The exponent of the simplified power is 3

Step-by-step explanation:

The original question is:

\frac{6^7}{6^4}

Required

- Express the exponents in expanded form

- Divide common factors

We have:

\frac{6^7}{6^4}

In indices:

x^2 = x * x

So, the above expression becomes:

\frac{6^7}{6^4} = \frac{6*6*6*6*6*6*6}{6*6*6*6}

Divide the common factors, to give:

\frac{6^7}{6^4} = 6*6*6

Express as an exponent

In indices;

x * x * x = x^3

So, we have:

\frac{6^7}{6^4} = 6^3

<em>The simplified power is </em>6^3<em> and 3 is the exponent</em>

5x + 3 = 7x – 1. Find x
nasty-shy [4]

Answer:

x = 2

Step-by-step explanation:

5x + 3 = 7x - 1

Subtract 3 to both sides

5x = 7x - 4

Subtract 7x to both sides

-2x = -4

Divide by -2 to both sides.

x = 2

Hope this helps and pls do mark me brainliest if you can:)
