expand sqrt(5(2.5)^3-3(2.5)^2-6(2.5)-16)

expand

5 (2.5)^{3} - 3 (2.5)^{2} - 6 (2.5) - 16

5.32681 \dots

Solution steps

5 \cdot 2. 5^{3} - 3 \cdot 2. 5^{2} - 6 (2.5) - 16

Remove parentheses:

(a) = a

= 5 \cdot 2. 5^{3} - 3 \cdot 2. 5^{2} - 6 \cdot 2.5 - 16

Multiply the numbers:

6 \cdot 2.5 = 15

= 5 \cdot 2. 5^{3} - 3 \cdot 2. 5^{2} - 15 - 16

Subtract the numbers:

- 15 - 16 = - 31

= 5 \cdot 2. 5^{3} - 3 \cdot 2. 5^{2} - 31

5 \cdot 2. 5^{3} = 78.125

3 \cdot 2. 5^{2} = 18.75

= 78.125 - 18.75 - 31

Subtract the numbers:

78.125 - 18.75 - 31 = 28.375

= 28.375

28.375 = 5.32681 \dots

= 5.32681 \dots

\frac{( x - 1 ) \cdot ( x - 2 )}{( x + 3 ) \cdot ( x + 4 )}

\frac{- x ^{2} + 1 - 1}{x ( x ^{2} + 1 + x ^{2} + 1 )}

\frac{2 ( x ^{4} - 3 x ^{3} + 1 )}{x ^{2}}

sin (\frac{( 2 k + 1 ) π}{2})

\frac{( 32 y + 1 ) ^{2}}{16}
