Solve the following logarithmic equations.<br> 5 log(x + 4) = 10

Ede4ka [16]

Answer:

$x=e^{2} -4$

Step-by-step explanation:

Divide both sides by 5:

$log(x+4)=\frac{10}{5} \\log(x+4)=2$

Cancel logarithms by taking exp of both sides:

$e^{log(x+4)}=e^{2} \\x+4=e^{2}$

Solve for x subtracting 4 from both sides:

$x=e^{2} -4$

5√5 can be written in the form <img src="https://tex.z-dn.net/?f=5%5E%7Bk%7D" id="TexFormula1" title="5^{k}" alt="5^{k}" align="

BigorU [14]

Answer:

n=3/2

Step-by-step explanation:

5 = 5^(1/2)

5√5 = [5^1] * [5^(1/2)]

when you multiply you add exponents

5√5 = 5^(1 + 1/2)

but 1 = 2/2

5√5 = 5^[(2/2) + (1/2)] = 5^[3/2]
