What is x and y if 2^x times 3^x is 1296

x≈4

Step-by-step explanation:

We are given that

And we are asked to solve it for x

In order to do that we will use the properties of logarithm

Taking log on both hand sides

----------------(A)

We know that

Hence applying this law in (A)

--------------(B)

Another property of logarithm says

Applying this law in (B)

taking x as GCF

Dividing both sides by \log 6[/tex]

using calculator

log 1296 = 3.1126

log 6 = 0.7781

x≈4

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
