Question

solve the equation 9=square root of 3 ^(4x+6)Using complete sentences, explain the strategy used in solving this equation.

Answer 1

those online courses are soo nitpicky arent they :)

Answer 2

yes:(

Answer 3

hard to parse the equation ..... for me that is

Answer 4

9=¨3^2

Answer 5

If you go back and look at the other 2 questions u posted like this, the way to do it will become clear...

Answer 6

9=square root of 3 ^(4x+6)
on squaring both sides
=> square of 9 = square of [ square root of 3 ^(4x+6) ]
=> 81 = 3^(4x+6)
=> 3^4 = 3^(4x+6)
=> 4 = 4x+6 //since a^x = a^y .=> x=y
=> 4x+6 = 4
=> 4x = 4-6
=> 4x = -2
=> x = -2/4 // dividing with 4 on both sides
=> x = -1/2
=> x = -0.5

Answer 7

thank u!!!!!!!!!

Answer 8

OMG...

Answer 9

okay i get it now!

Answer 10

3^2 = 3^(4x+6) SO

2 = 4x +6 -> x = -1

Answer 11

i like the way u explained it and put it out thanks!

Answer 12

u r welcome
