Evaluate each expression. Enter the correct answers in the boxes. (60−6)×(13)3+27÷3= ( 60 − 6 ) × ( 1 3 ) 3 + 27 ÷ 3 = 82÷4×(2+3
11Alexandr11 [23.1K]

Answer:

2115

Explanation:

To evaluate the expression (60−6)×(13)3+27÷3 we use BODMAS

BODMAS is an acronym/rule in mathematics that dictates the order we should solve mathematical operations such as the above.

BODMAS stands for bracket first, order or of, division, multiplication, addition and then lastly subtraction

To solve the expression using BODMAS, we solve the brackets first

(60−6)×(13)3+27÷3 =54×39+27/3

Then division

=54×39+9

=2106+9

Then addition

=2106+9=2115

Answer=2115

Daniel is looking over some data regarding the temperatures of countries and how the temperature relates to the number of mosqui
Doss [256]

The logarithmic function when the temperature is 64 degrees is given as
ln f(x) = x ln 2.

<h3>What is a logarithmic function?</h3>

A logarithmic function is the inverse of an exponential function. It is to be noted that all exponential functions can be written as logarithmic functions.

Hence, to convert the mathematical statement above into a logarithmic function we say:

f(x) = 2ˣ

ln f(x) = ln 2ˣ

ln f(x) = x ln 2

Ln 64 = x Ln 2

Let f(x) = 64;

Hence,

Ln 64 = x ln 2

Divide both sides by  ln 2 to get x

ln 64/ln 2 = x

Hence,

x = ln 64/ln 2

= 6
