Question

62500:{502:[112-(52-23.5)]}

Answer 1

\(=\dfrac{62500}{502:\left[112-52+115\right]}=\dfrac{62500}{502:175}\simeq21787,84861\)

Answer 2

\(62500:\left\{502:\left[112-\left(52-23.5\right)\right]\right\}\\ =62500:\left\{502:\left[112-\left(52-115\right)\right]\right\}\\ =62500:\left\{502:\left[112-\left(-63\right)\right]\right\}\\ =62500:\left\{502:175\right\}\\ =62500:\dfrac{502}{175}\\ =21787,84861\)

Answer 3

\(62500:\left\{502:\left[112-\left(52-23.5\right)\right]\right\}\)

\(=62500:\left\{502:\left[112-\left(52-115\right)\right]\right\}\)

\(=62500:\left\{502:\left[112-\left(-63\right)\right]\right\}\)

\(=62500:\left(502:175\right)\)

\(=62500:\dfrac{502}{175}\sim21788\)
