Question

how can exponential equations with unequal bases be solved ?? please help

Answer 1

Your question ?

Answer 2

that was what i was asked … i dont get it either

Answer 3

Is it about logarithms ? or just exponents ?

Answer 4

exponential and logarithms yah

Answer 5

a^m x b^m = (ab)^m
is it this?

Answer 6

Okay, (usually) you would try to make all the bases equal to base 10

USING, \(\LARGE\color{black}{ \log_AB=\frac{\log_{10}B}{\log_{10}A}}\)

Answer 7

ok im followin you … so thats the formula

Answer 8

Yes:)

Answer 9

I don't like these type of questions though, I like specific questions better.

Answer 10

Do you want a little mathematical riddle after we do this question?

Answer 12

haha amd sure why not

Answer 13

Okay, but now you figured.. ?

Answer 14

Okay the riddle is (typing it)

Answer 15

The ball is falling from a certain height (lets say 20 feet) and bounces on 80 percent of the height. For 100 bounces, what is the way to find THE FULL VERTICAL HEIGHT that the BALL FLEW.

Answer 16

(get the riddle ? )

Answer 17

no clue lol

Answer 18

Hint: Geometric sequence.

Answer 19

Still confused ?

Answer 20

see I really have no clue im so bad at math im trying to pass this class and ill be done finally lol

Answer 21

im thinking thow

Answer 22

\(\normalsize\color{black}{ 2 S_n-(a_1-a_{100}) }\)

Answer 23

There are 100 of different heights, where all of them are a1 a2 a3 ... a99 a100 right ?

Answer 24

yah

Answer 25

Okay, and all the heights it goes through, it goes through twice up and down, besides a1 and a100,

because a1 is only once (one time down)
and a100 is only once (one time up)

Answer 26

a1 is the begging of the first bounce, and a100 is the end of the last one.

Answer 27

Well, anyway, I don't want to overwhelm you... good luck :)

Answer 28

thank you so much!
