Question

Helppppppp plsssssss

.
We know, for example, that (2+3)+5=2+(3+5) and 2 (3-5) = (2-3). 5. The
grouping with parentheses does not affect the value of the expression.
Is this true for exponents? That is, are the numbers 2(3³).
(23) equal? If not, which is
bigger? Which of the two would you choose as the meaning of the expression 2.3 writter
without parentheses?

Answer 1

Answer: No, the numbers 2(3³) and (23) are not equal.

2(3³) means 2 multiplied by 3 raised to the power of 3, which is equal to 2 times 27, or 54.

(23) means 2 raised to the power of 3, and then that result raised to the power of 2, which is equal to 8 raised to the power of 2, or 64.

So, (23) is bigger than 2(3³).

If we write 2.3 without parentheses, it could be interpreted in two different ways: as the product of 2 and 3, which is 6, or as the number 23. To avoid confusion, it's important to use parentheses or other grouping symbols to indicate the intended meaning of an expression.
