X² -12x -64=0
D=b² - 4ac=144+4*64=400

x=(-b+/-√D)/2a

x=(12+/-20)/2
x1=32/2=16
x2=-8/2= -4

1=10^0 into logarithmic form

Tatiana [17]

Answer:

$0 = log_{10} 1$

Step-by-step explanation:

Base for the exponent and for the logarithm are the same!

10^0 is the <u>exponential</u> form where 10 is the base and 0 the exponent

$log_{10} 1$ is the l<u>ogarithm</u> form where 10 is the base

To solve $log_{10} 1 =$ ask the question :

To what power should I raise the base 10 to obtain the number 1 ?

The answer to the power 0 therefore

$log_{10} 1 = 0$

$1 = 10^{0} -is-the- exponential -form\\0 = log_{10} 1 - is -the -logarithmic -form$
