Question

6^5x=20 round to the nearest ten-thousands

Answer 1

Ok so 6^5
6x6x6x6x6 = 7776

7776x=20

Then we divide each side by 7776

7776x = 20
——— ———
7776 7776


X= 0.00257202


Estimate: 0

Answer 2

I think you're saying that the exponent is (5x), and the equation is

6⁵ˣ = 20 .

IF so, then . . .

Take the log of each side: 5x·log(6) = log(20)

Divide each side by log(6) : 5x = log(20) / log(6)

Divide each side by 5 : x = 0.2 log(20) / log(6)

x = 0.2 · (1.30103) / (0.77815)

x = 0.33439
