Answer:
C (√10)/2
Step-by-step explanation:
Multiply numerator and denominator by √10. Then you have ...
... (5√10)/10 = (√10)/2
_____
Of course, you can always compare the given answers by using your calculator.
5/√10 ≈ 1.58114
The answer choices are ...
... A: 1.41421
... B: 2.23607
... C: 1.58114 . . . . matches the given expression in value
... D: 0.707107
_____
If you're familiar with the square roots of small integers, you can do this last exercise in your head once you have calculated 5/√10. That is, you can eliminate choices A, B, and D.
... √2 ≈ 1.414; √3 ≈ 1.732; √5 ≈ 2.236
Answer:
x=ln(61)/ln(4)
Step-by-step explanation:
4^x+3=64
4^x=64-3
4^x=61
x=ln(61)/ln(4)
X = 5/2 ,y = 1.I usually solve for x first then substitute the answer in one of the equations to find y.
