Rewrite the expression in the form 7^n<br><br> 7^2 x 7^6

s2008m [1.1K]

Answer:

The expression in the form $7^n$

$7^2\times \:\:7^6=7^n$

Step-by-step explanation:

$7^2\:\times \:7^6$

$\mathrm{Apply\:exponent\:rule}:\quad \:a^b\times \:a^c=a^{b+c}$

$7^2\times \:7^6=7^{2+6}$

So the expression becomes

$7^2\:\times \:7^6=7^{2+6}$

$=7^{2+6}$

Add the numbers: 2+6=8

$=7^8$

Therefore, the expression in the form $7^n$

$7^2\times \:\:7^6=7^8$
