Given the exponential equation 4x = 64, what is the logarithmic form of the equation in base 10?

zysi [14]

$4^{x} = 64$

By taking <span>logarithmic of base 10

∴ </span><span> $log 4^{x} = log 64$

∴ x log 4 = log 64

∴ $x = \frac{log \ 64}{log \ 4}$
note: we don't need to write the base in case of the base =10

∴ The correct choice is
</span><span>x = log base 10 of 64, all over log base 10 of 4</span>

Enzo and Beatriz are playing games at their local arcade. Incredibly, Enzo wins 55 tickets from every game, and Beatriz wins 111

madam [21]

Answer:

101

Step-by-step explanation:

Note that

$55=5\cdot 11;$
$1111=11\cdot 101.$

Here these two numbers have the common divisor 11. Find the least common multuply:

$LCM(55,1111)=11\cdot 5\cdot 101=5555.$

This means that the minimum number of games that Enzo could have played will be

$\dfrac{5555}{55}=101.$
