${a}^{x} = m \\ log_{a}(m) = x$

$( \frac{1}{3} )^{x} = 27 \\ log_{ \frac{1}{3} }(27) = x$

That's the logarithmic form. Do you need with solving the equation too?

Simplify -12u + 11z “Enter the original expression if it cannot be simplified”

jeka94

Answer:

-12u + 11z

Step-by-step explanation:

The above expression cannot be simplified, for:

1) There is no common variable (one being u, and the other being z).

2) There are no common factors in between 12 & 11)

- Factors of 12: 1, 2, 3, 4, 6, 12

- Factors of 11: 1, 11

How do you know that the sum of 7-1g and 7-2 is rational?

user100 [1]

The sum of 7-1 and 7-2 will be a rational number because sum of rational numbers is a rational numbers.

A rational number is a number which can be written in p/q form where q≠0.

We know that when two rational numbers is added then the sum is also a rational number. And when two rational numbers are subtracted then the difference is also a rational number.

So in the given question, lets study the term differently that is,

i) 7 - 1 is a rational number because their difference is equal to 6 and it can be written in p/q form which is 6/1.

ii) 7 – 2 is also a rational number as their difference will be 5 which is a rational and can be written in p/q form which is 5/1.

So when these two rational numbers are added their sum will also be a rational number which is 11.
