Exponentials and Logarithms

How do you solve 2x+1=642^{x+1}=642x+1=64 without using logarithms?

A
  • Rewrite 64 as 262^626
  • Equate indices: x=6ext</li><li>x=6 ext{}</li><li>x=6ext</li><li>x=6$
B
  • Rewrite 64 as 262^626
  • Equate indices: x+1=6x+1=6x+1=6
  • x=7x=7x=7
C
  • Rewrite 64 as 262^626
  • Equate indices: x+1=6x+1=6x+1=6
  • x=5x=5x=5
D
  • Rewrite 64 as 252^525
  • Equate indices: x+1=5x+1=5x+1=5
  • x=4x=4x=4
