Question

help with simplifying logs and exponential functions? one is: logbase5(10)+logbase25(10)?

Answer 1

=logbase5(10)+((logbase5(10))/(logbase5(25)))
=logbase5(10)+((logbase5(10))/(logbase5(5^2)))
=logbase5(10)+((logbase5(10))/(2logbase5(5)))
=logbase5(10)+((logbase5(10))/(2*1))
=1.5logbase5(10)

let me kno if need further simplification

Answer 2

the answer on this sheet says 3/(2log5)?

Answer 3

=1.5 (log10/log5)
=1.5(1/log5)
=3/2(1/log5)
3/(2log5)

Answer 4

ohhh okay! coudl you help me with another?

Answer 5

ok, lets see if am able to solve

Answer 6

okay. (e^x - e^-x)^2 / e^(2x)?

Answer 7

=(e^2x-2e^xe^-x+e^-2x)/e^2x
=(e^2x-2+e^-2x)/e^2x
=(e^2x/e^2x)-(2/e^2x)+(e^-2x/e^2x)
=1-2e^-2x+e^-4x

Answer 8

does it correspond to the answer

Answer 9

(1-e^-2x)^2 is the answer

Answer 10

only one step further
1-2e^-2x+e^-4x=(1-e^-2x)^2

Answer 11

ohhh okay. one more?

Answer 12

sorry me going nxt time
am reaallllllllllllllyyyyyyyyyyyyyyyyyy soooooooooooorrrrrrrrrrrrrrrrrrryyyyyyyy

Answer 13

its okay! thanks!

Answer 14

post it nxt time i come i answer
if u wouldnt hav already obtain the answer

Answer 15

ok!
