Answer:

b = -1

Step-by-step explanation:

Your equation is ...

(5^3)b -1 = 5^b -3

This is a mix of exponential and linear terms, and cannot be solved algebraically.

___

We suspect you might mean ...

5^(3b -1) = 5^(b -3)

We can equate the exponents to find a value for b:

3b -1 = b -3

2b = -2 . . . . add 1-b to both sides

b = -1 . . . . . . divide by 2

What is the value of x

pochemuha

This is the isosceles triangle. Therefore, the angles at the base are congruent.

We know that the sum of the measures of the angles in a triangle is 180°.

Therefore we have the equation:

$38^o+x^o+x^o=180^o$

$38^o+2x^o=180^o$ <em>subtract 38 from both sides</em>

$2x^o=142^o$ <em>divide both sides by 2</em>

$x^2=71^o$

<h3>Answer: x = 71.</h3>
