Question

Answer 1

a: \(=\dfrac{11}{24}+\dfrac{13}{24}-\dfrac{5}{41}-\dfrac{36}{41}+\dfrac{1}{2}=\dfrac{1}{2}\)

b: \(=-12:\left(\dfrac{9}{12}-\dfrac{10}{12}\right)^2=-12\cdot144=-1368\)

c: \(=\left(4\cdot\dfrac{3}{4}-\dfrac{1}{2}\right)\cdot\dfrac{6}{5}-17=\dfrac{5}{2}\cdot\dfrac{6}{5}-17=3-17=-14\)

d: \(=\dfrac{2^{10}\cdot3^9-2^9\cdot3^8}{2^{10}\cdot3^8}=\dfrac{2^9\cdot3^8\left(2\cdot3-1\right)}{2^{10}\cdot3^8}=\dfrac{1}{2}\cdot5=\dfrac{5}{2}\)

g: =8+2*3-7*1,3+3*5/4

=14-9,1+15/4

=4,9+3,75=8,65
