81^5=3^x What does “x” equal?
Lynna [10]

Answer:

x =2 0

Step-by-step explanation:

{81}^{5}  =  {3}^{x}

We know that 3^4 = 81. So :

=  >  { ({3}^{4}) }^{5}  =  {3}^{x}

=  >  {3}^{4 \times 5}  =  {3}^{x}

=  >  {3}^{20}  =  {3}^{x}

Here both the Right hand side & Left hand side has same base i.e. have 3 as base in both the sides.

So , eliminating the base gives :-

x = 20

Ber [7]

The expression that is equivalent to the given expression is -4x^-5

<h3>How to determine which expression is equivalent to the given expression?</h3>

The expression is given as:

-4x^{-5} x^{0}

Rewrite properly as

-4x^-5x^0

Express as products

-4x^-5 * x^0

The value of x^0 is 1

So, we have:

-4x^-5 * 1

Evaluate the product

-4x^-5

Hence, the expression that is equivalent to the given expression is -4x^-5
