Question

Find a if
(3.5)*(3.5)6
(3.5)
8
x =
=
(3.5)7

Answer 1

The expression seems a bit unclear due to formatting. Let me interpret it as follows:

\[ x = \frac{{(3.5 \times 3.5)^6 \cdot (3.5)^8}}{{(3.5)^7}} \]

Now, simplify this expression:

\[ x = \frac{{(12.25)^6 \cdot (12.25)^8}}{{12.25^7}} \]

Combine the exponents with the same base:

\[ x = \frac{{12.25^{6+8}}}{{12.25^7}} \]

Now, subtract the exponents:

\[ x = 12.25^{14-7} \]

\[ x = 12.25^7 \]

So, \( x \) is equal to \( 12.25^7 \). If you want a numerical value, you can calculate it.
