simplify (((-2.81)^2)/((1.9)^2))(0.5(1-0.5))

simplify

(\frac{( - 2.81 ) ^{2}}{( 1.9 ) ^{2}}) (0.5 (1 - 0.5))

0.54682 \dots

Solution steps

(\frac{( - 2.81 ) ^{2}}{( 1.9 ) ^{2}}) (0.5 (1 - 0.5))

Apply exponent rule:

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

\frac{( - 2.81 ) ^{2}}{1. 9 ^{2}} = (\frac{- 2.81}{1.9})^{2}

= 0.5 (\frac{- 2.81}{1.9})^{2} (1 - 0.5)

(\frac{- 2.81}{1.9})^{2} = \frac{2.8 1 ^{2}}{1. 9 ^{2}}

= 0.5 \cdot \frac{2.8 1 ^{2}}{1. 9 ^{2}} (1 - 0.5)

Subtract the numbers:

1 - 0.5 = 0.5

= 0.5 \cdot 0.5 \cdot \frac{2.8 1 ^{2}}{1. 9 ^{2}}

Multiply the numbers:

0.5 \cdot 0.5 = 0.25

= 0.25 \cdot \frac{2.8 1 ^{2}}{1. 9 ^{2}}

Multiply fractions:

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

= \frac{2.8 1 ^{2} \cdot 0.25}{1. 9 ^{2}}

2.8 1^{2} \cdot 0.25 = 1.974025

= \frac{1.974025}{1. 9 ^{2}}

1. 9^{2} = 3.61

= \frac{1.974025}{3.61}

Divide the numbers:

\frac{1.974025}{3.61} = 0.54682 \dots

= 0.54682 \dots

(8.99 \cdot 1 0^{9}) 23 \cdot 1 0^{- 9}

x + 5 \cdot x - 5

(2 - 3)^{2^{^{'}}}
