Take the ln of both sides
remember
ln(a^x)=xln(a)
so

ln(2^x)=ln(22.5)
xln(2)=ln(22.5)
divide both sides by ln2
x=ln(22.5)/ln(2)
if you want to evaluate
use calculator
x=4.49185

Vinvika [58]

Answer:

  • -2
  • 24
  • 6
  • -36

Step-by-step explanation:

Put the numbers in place of the corresponding letter and do the arithmetic.

  y -10 = 8 -10 = -2

  12 -z = 12 -(-12) = 24

  3 -x = 3 -(-3) = 6

  z -24 = -12 -24 = -36
