Simplify 81^5 = 3^х x=

The answer for the value of x is, x=20

X = 20

Step-by-step explanation:

3^4 = 81

exponent 4 x 5 = 20

so 3^20 = 81^5

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
