Step-by-step explanation:
The given expression -8 ÷ 343 can situationaly be written in power notation as -8 ÷ 7^3. This transformation changes '343' to '7^3' since 343 is 7 cubed.
The expression -8 ÷ 343 cannot be directly written in 'power notation', as the concept of'power notation' commonly refers to writing an expression in the form of a base value raised to an exponent.
Power notation is typically represented as a^n, where 'a' is the base and 'n' is the exponent. However, '343' can be written in power notation since it is 7 cubed (7^3).
So, while we should clarify the details, one way to write the expression could be -8 ÷ 7^3.

Step-by-step explanation:?
The equation for the number of beats per minute is 55 beats per minute
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the total number of beats be = A
Now , the value of A = 220 beats
The total time required for Sam to have 220 beats = 4 minutes
So , the number of beats of Sam in 1 minutes is calculated by
The equation will be
The number of beats of Sam in 1 minutes is = total number of beats / total time required for Sam to have 220 beats
The number of beats of Sam in 1 minute is = 220 / 4
The number of beats of Sam in 1 minute is = 55 beats per minute
Therefore , Sam would have 55 beats every minute or 55 beats per minute
And for the period of 4 minutes , Sam would have
Number of beats for 4 minutes = number of beats of Sam in 1 minute x 4
Number of beats for 4 minutes = 55 x 4
Number of beats for 4 minutes = 220 beats in 4 minutes
Hence , The equation for the number of beats per minute is 55 beats per minute
