Question

What is the solution to the equation 21 ^x – 3 = 14 ?

Answer 1

i would double check that

Answer 2

21^x-3=14

sum both sides 3

21^x=17

Put ln both sides(natural logarythm)

ln21^x=17

Put down the exponent.

xln21=17

divide both sides by ln21

x=ln17/ln21


Is ok now?

Answer 3

is the problem \[21^x-3 =14 \] or\[21^(x-3)=14\]

big difference

Answer 4

im sory i ment \[21^{x-3}\]

Answer 5

if it is the later you are in correct if its the first then you are correct

Answer 6

answer is ln17/ln21..would u like the explainations
