Question

if 4.23*52k=789.23 The value of of his​

Answer 1

Answer:

k=3.58806147 or 3.58

Explanation:

Answer 2

Given:

4.23 × 52k = 789.23

To Find:

The values of k

Solution:

• In this expression, "k" is a variable term.
• The value of k can be determined by making it the subject of the expression.

This can be done by using the inverse of the function associated to the variable (k) on the whole expression.

In this case

LHS is

4.23 Multiplied by 52k

RHS is

789.23

• Inverse of the function (multiplication) used in LHS is division.
• Therefore divide both sides by the value that is Multiplied i.e 4.23

4.23 × 52k = 789.23

(4.23 × 52k) ÷ 4.23 = 789.23 ÷ 4.23

52k = 186.5791962175 ≈ 186.58 (Rounded to 2 decimal places)

We get,

52k = 186.58

We can write 52k as 52×k

So,

To make k the subject divide the whole expression by 52

52k ÷ 52 = 186.58 ÷ 52

k = 3.5880769231 ≈ 3.59 (Rounded to 2 decimal places)

Hence, the values of k is 3.59.
