Exponent - An exponent refers to the number of times a number is multiplied by itself. For example, 2 to the 3rd (written like this: 2³)
2 x 2 x 2 = 8.
2³ is not the same as 2 x 3 = 6.
Based on the given above it's 15 and it's multiplied by 3 which means 15³.
Answer: The expression for the volume using exponents of 15 cm long, 15 cm wide and 15 cm tall is 15³.

MDAS - Stands for Multiplication, Division, Addition, and Subtraction. It is part of the Order of Operations, a collection of rules that gives a sequence for simplifying mathematical operations. It is used when an expression or equation has more than one operation.
Divide 21 by 3 then Multiply by 4 then Substract by 28 like the procedure below:
21 ÷ 3 x 4 - 28 =
7 x 4 - 28 =
28 - 28 = 0
Answer: 0 is the answer.
Solution 3:
Divide 1566 by 27 and then Multiply it by 4 like the procedure below:
1566 ÷ 27 = 58
58 x 4 = 232
