Answer 2

Answer:

The value of x is 3.

Step-by-step explanation:

We have to find :

• Value of x

Given equation :

• $-3^{8}$÷ $-3^{5} = -3^{x}$

Using the property :

• $x^a$  ÷ $x^b = x^{a-b}$

So :

• $-3^{8-(+5)} = -3^x$
• $-3^{8-5} = -3^x$
• $-3^3 = -3^x$

Change negative (-3) into positive (3) :

• $[\frac{1}{3} ]^3 = [\frac{1}{3} ]^x$        [  $-a = \frac{1}{a}$  ]

When bases are same we equate powers :

• $3=x$

The value of x is 3.
