1/2 (2)^3

Solution

\frac{1}{2} (2)^{3}

4

Solution steps

\frac{1}{2} (2)^{3}

Follow the PEMDAS order of operations

Calculate exponents

(2)^{3} : 8

(2)^{3}

(2)^{3} = 8

= 8

= \frac{1}{2} \cdot 8

Multiply and divide (left to right)

\frac{1}{2} \cdot 8 : 4

\frac{1}{2} \cdot 8

Convert element to fraction:

8 = \frac{8}{1}

= \frac{1}{2} \cdot \frac{8}{1}

Apply the fraction rule:

\frac{a}{b} \cdot \frac{c}{d} = \frac{a \cdot c}{b \cdot d}

= \frac{1 \cdot 8}{2 \cdot 1}

\frac{1 \cdot 8}{2 \cdot 1} = 4

\frac{1 \cdot 8}{2 \cdot 1}

\frac{1 \cdot 8}{2 \cdot 1} = \frac{8}{2}

\frac{1 \cdot 8}{2 \cdot 1}

Multiply the numbers:

1 \cdot 8 = 8

= \frac{8}{2 \cdot 1}

Multiply the numbers:

2 \cdot 1 = 2

= \frac{8}{2}

= \frac{8}{2}

Divide the numbers:

\frac{8}{2} = 4

= 4

= 4

= 4

2 \cdot 3^{3} \div 9

- 2 - \frac{1}{4} (- \frac{4}{5})

18 \div 9 + 2 \cdot 6

3^{3} \times 3
