MULTIPLE CHOICE QUESTION

30 sec • 1 pt

Rewrite the following expression in logarithmic form:

823=48^{\frac{2}{3}}=4  

log⁡8(23)=4\log_8\left(\frac{2}{3}\right)=4  

log⁡4(8)=23\log_4\left(8\right)=\frac{2}{3}  

log⁡23(4)=8\log_{\frac{2}{3}}\left(4\right)=8  

log⁡8(4)=23\log_8\left(4\right)=\frac{2}{3}

MULTIPLE CHOICE QUESTION

Rewrite the following expression in exponential form:

log⁡5(125)=−2\log_5\left(\frac{1}{25}\right)=-2  

(−2)5=125\left(-2\right)^5=\frac{1}{25}  

5125=−25^{\frac{1}{25}}=-2  

5−2=1255^{-2}=\frac{1}{25}  

(125)−2=5\left(\frac{1}{25}\right)^{-2}=5  

(−2)125=5\left(-2\right)^{\frac{1}{25}}=5
