SORRY LÀ CALCULARTOR

a) \(536.27-\left(825+219\right):18+15^3:15^2-4^2.3\)

\(=526.27-1044:18+15-16.3=14202-58+15-48\)

\(=\left(14202+15\right)-\left(58+48\right)=14217-106=14111\)

b) \(120-\left[5871:103+3^2.2-\left(9^0+1^{10}+6\right):2^3\right]\)

\(=120-\left[57+9.2-\left(1+1+6\right):2^3\right]\)

\(=120-\left[57+18-8:8\right]=120-74=46\)

c) \(-|-5|+\left(-19\right)+\left(-18\right)+|11-4|-57\)

\(=\left(-5\right)-19-18+7-57=\left(-42\right)+\left(-50\right)=-92\)

a) 773773

b) 13

c) -56

a) \(\dfrac{27^3\cdot11+9^5\cdot5}{3^9\cdot2^4}\)

\(=\dfrac{3^9\cdot11+3^{10}\cdot5}{3^9\cdot2^4}\)

\(=\dfrac{3^9\cdot\left(11+3\cdot5\right)}{3^9\cdot2^4}\)

\(=\dfrac{11+15}{16}\)

\(=\dfrac{26}{16}\)

\(=\dfrac{13}{8}\)

b) \(\dfrac{5^8+2^2\cdot25^4+2^3\cdot125^3-15^4\cdot5^4}{4^2\cdot625^2}\)

\(=\dfrac{5^8+2^2\cdot5^8+2^3\cdot5^9-3^4\cdot5^4\cdot5^4}{2^4\cdot5^8}\)

\(=\dfrac{5^8\cdot\left(1+2^2+2^3\cdot5-3^4\right)}{5^8\cdot2^4}\)

\(=\dfrac{1+4+40-81}{16}\)

\(=\dfrac{-36}{16}\)

\(=\dfrac{-9}{4}\)

c) \(\dfrac{4^5\cdot9^4-2\cdot6^9}{2^{10}\cdot3^8+6^8\cdot20}\)

\(=\dfrac{2^{10}\cdot3^8-2\cdot2^9\cdot3^9}{2^{10}\cdot3^8+2^{10}\cdot3^8\cdot5}\)

\(=\dfrac{2^{10}\cdot3^8\cdot\left(1-3\right)}{2^{10}\cdot3^8\cdot\left(1+5\right)}\)

\(=\dfrac{-2}{6}\)

\(=-\dfrac{1}{3}\)

536x27-(825+219):18+15³:15²-4²x3

=536x27-(825+219):18+15¹-16x3

=536x27-1044:18+15-16x3

=14472-58+15-48

=14414+15-48

=14429-48

=14381

a) (5² + 1) - 9.3

= 26 - 9.3

= 16.7

b) 80 - (4.5² - 3.2³)

= 80 - (20.25 - 32.768)

= 80 - (-12.518)

= 92.518

c)[(-18) + (-7)] -15

= -25 - 15

= -40

d) (-219) - (-229) + 12.5

= 10 + 12.5

= 22.5

Tick cho mik nhé

mình cần gấp lắm

giúp mình nha
