4^x+6^x =9^x​

Answers

4^x + 6^x = 9^x

4^x + 6^x - 9^x = 0

2^2x + (2×3)^x - 3^2x = 0

2^2x + 2^x×3^x - 3^2x = 0

(⅔)^2x + (⅔)^x - 1 = 0

let t = ( ⅔)^x

t² + t - 1 = 0

t = (-1+√5 ) / 2

(⅔)^x = (-1+√5 ) / 2

x = Log base ⅔ ((-1+√5 ) / 2 )

What percentage of his monthly budget does Doug put in savings?

O A. 13%

B. 6%

C. 11%

D. 16%

To get the percentage of his monthly budget does Doug put in savings, first we need to get the total savings

Total savings = 403+806+868+496+341+186

Total money = $3100

Amount spent on savings = $341

Percentage savings = amount spent on savings/Total money × 100%

Percentage savings = 341/3100 × 100

Percentage savings = 341/31

Percentage savings = 11%

Hence the percentage of the total money spent on savings is 11%

The Equivalent value of 2 log x + log 11 is log(11x²).

What is Logarithm?

The power to which a number must be increased in order to obtain additional values is referred to as a logarithm. The easiest approach to express enormous numbers is this manner. Numerous significant characteristics of a logarithm demonstrate that addition and subtraction logarithms can also be represented as multiplication and division of logarithms.

We have to find the value of 2 log x + log 11.

Using the property

log a + log b = log (ab)

and, 2 log a = log a²

So, 2 log x + log 11

= log x² + log 11

= log( x² × 11)

= log(11x²)
