\frac{5 0 ^{2} - 8 0 ^{2}}{2}

- 1950

Solution steps

\frac{5 0 ^{2} - 8 0 ^{2}}{2}

Solve

5 0^{2} - 8 0^{2} : - 3900

Follow the PEMDAS order of operations

Calculate exponents

5 0^{2} : 2500

5 0^{2}

5 0^{2} = 2500

= 2500

= 2500 - 8 0^{2}

Calculate exponents

8 0^{2} : 6400

8 0^{2}

8 0^{2} = 6400

= 6400

= 2500 - 6400

Add and subtract (left to right)

2500 - 6400 : - 3900

2500 - 6400

2500 - 6400 = - 3900

= - 3900

= - 3900

= \frac{- 3900}{2}

Simplify

\frac{- 3900}{2} : - 1950

Apply the fraction rule:

\frac{- a}{b} = - \frac{a}{b}

= - \frac{3900}{2}

Divide the numbers:

\frac{3900}{2} = 1950

= - 1950

= - 1950
