Hello was wondering if someone could help me with this
.
7^t * 4^3t-3 = 4^t+1 * 7^3t-1

Find the value of t

Cheers

This?

[nuodai]

Take logarithms; what you get is a linear equation in that can be solved by rearranging.

[dezzi90]

can you explain this further?

[gupta-mhm-mhm-mhm]

I think t = 9?

[gupta-mhm-mhm-mhm]

Oh wait no its not, my bad

you're not meant to give solutions...


OP do you know how to take logs? and you can do some obvious rearranging before taking logs

Have you learnt about logarithms?

[dezzi90]

i rearranged to 7^(t)-(3t-1)=4^(t+1)-(3t-3)

[dezzi90]

wouldnt know how to long this i would end up with a few equals signs i would have thought
