Exponentials and Logarithms

Card 1 of 21

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

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