Use grouping symbols and at least one exponent to write a numerical expression that has a value of 80.
Kaylis [27]

To group an expression, means that the factors of the expression are to be separated in (), [] or {}.

An expression with a value of 80 is: 2^2 \times ( [2 + 2] \times [3 + 2] )

The number is given as:

80

Factorize

80 = 2 \times 40

Factorize 40

80 = 2 \times 2 \times 20

Express 2 \times 2 as an exponent

80 = 2^2 \times 20

Express 20 as 4 x 5

80 = 2^2 \times ( 4 \times 5)

Express 5 as 3 + 2

80 = 2^2 \times ( 4 \times [3 + 2] )

Express 4 as 2 + 2

80 = 2^2 \times ( [2 + 2] \times [3 + 2] )

Hence, the above expression has a numerical value of 80
