Answer:The depth of the submarine after 4 stages of rising to the surface will be 100 meters.
What is an expression?
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
It is given that a submarine is only allowed to change its depth by rising toward the surface in 60-meter stages. The submarine starts off at 340 meters below sea level.
The depth of the submarine after 4 stages will be calculated as below:-
depth = 4 x 60 = 240
depth from the surface = 340 - 240 100 meters
Therefore, the depth of the submarine after 4 stages of rising to the surface will be 100 meters.
