Answer :

Certainly! Let's solve the given expression step-by-step.

Step 1: Understand the given expression

We start with the expression:

[tex]\[ \frac{7^2 \cdot 7^8}{7^4} \][/tex]

Step 2: Simplify the numerator

To simplify the numerator, we use the property of exponents which states that when multiplying two powers with the same base, we add their exponents. So:

[tex]\[ 7^2 \cdot 7^8 = 7^{2+8} = 7^{10} \][/tex]

Step 3: Simplify the entire expression

Now, we have the simplified numerator as [tex]\(7^{10}\)[/tex]. The given expression becomes:

[tex]\[ \frac{7^{10}}{7^4} \][/tex]

To simplify this, we use the property of exponents which states that when dividing two powers with the same base, we subtract the exponents. So:

[tex]\[ \frac{7^{10}}{7^4} = 7^{10-4} = 7^6 \][/tex]

Step 4: Identify the values of [tex]\(a\)[/tex] and [tex]\(b\)[/tex]

According to the given format [tex]\(\frac{7^a}{7^4} = 7^b\)[/tex], we can compare:

- From the numerator, we see that:

[tex]\[ 7^a = 7^{10} \Rightarrow a = 10 \][/tex]

- From the simplified exponent:

[tex]\[ 7^6 \Rightarrow b = 6 \][/tex]

Therefore, the values are:

[tex]\[ a = 10, \quad b = 6 \][/tex]

Thus:

[tex]\[ \boxed{(a = 10, \quad b = 6)} \][/tex]
