Rewrite 4 1/2=2 <br> please
Luda [366]

The logarithmic expression of 4^(1/2) = 2 is \log_4(2) = \frac 12

<h3>How to rewrite the expression?</h3>

The expression is given as:

4^(1/2) = 2

Take the logarithm of both sides

log(4^(1/2)) = log(2)

Apply the change of base rule

1/2log(4) = log(2)

Divide both sides by log(4)

1/2 = log(2)/log(4)

Change the base

\frac 12 =\log_4(2)

Rewrite as:

\log_4(2) = \frac 12

Hence, the logarithmic expression of 4^(1/2) = 2 is \log_4(2) = \frac 12

MATH 30 POINTS WILL GIVE BRAINLIEST<br><br> help please
natulia [17]

The fundamental behavior that's important here is that, as t gets arbitrarily large, a^t becomes smaller (decays) if |a| and larger (grows) if |a|>1.

100\left(1-\dfrac12\right)^t=100\left(\dfrac12\right)^t\implies\dfrac12

0.1(1.25)^t\implies1.25>1\implies\text{growth}

426(0.98)^t\implies0.98

2050\left(\dfrac12\right)^t\implies\text{decay}

\left((1-0.03)^{1/2}\right)^{2t}=0.97^t\implies0.97
