15.2+4.3=?
2.3.4.5.6.7.8.9=?
15.2 + 4.3 = 30 + 12 = 42
2.3.4.5.6.7.8.9 = 362880
15.2+4.3=42
2.3.4.5.6.7.8.9=362880

80 - ( 4.5² -3.2³)
a, A = 110- (-761)+296+1454-(-813+1077)
b , B = 15.4^12.9^7-4.3^15.8^8/19.2^24.3^14-6.4^12.47^5
c , C = 2^50-2^49-2^48-2^47-...-2^2-2
a) A = 110 - (-761) + 296 + 1454 - (-813 + 1077)
= 110 + 761 + 296 + 1454 - 264
= 871 + 1750 - 264
= 2631 - 264
= 2357
15.23 + 4.32 - 5.7= ?
15*23+4*32-5*7
=15*8+4*9-35
=120+36-35=120+(36-35)=120+1=121
ta có: 15.23 + 4.32 - 5.7
= 15 . 8 + 4 . 9 - 35
= 120 + 36 - 35
= 120 - (36 - 35)
= 120 + 1 = 121
15.23+4.32.5.7
tính giúp mình cái
[-3/2]^3+-49/24.3/14-[5/8-27/8]
Ta có: \(\left(-\dfrac{3}{2}\right)^3+\dfrac{-49}{24}\cdot\dfrac{3}{14}-\left(\dfrac{5}{8}-\dfrac{27}{8}\right)\)
\(=\dfrac{-27}{8}+\dfrac{-7}{2}\cdot\dfrac{1}{8}-\dfrac{-22}{8}\)
\(=\dfrac{-27+22}{8}+\dfrac{-7}{16}\)
\(=\dfrac{-5}{8}+\dfrac{-7}{16}\)
\(=\dfrac{-10}{16}+\dfrac{-7}{16}\)
\(=\dfrac{-17}{16}\)
Ai muốn lì xì thì nhanh tay :
Tính A = 15.23 + 4.32 - 5.7 ( KHÔNG TRẢ LỜI LINH TINH )
A = 15.23 + 4.32 - 5.7
=> A = 15.8 + 4.9 - 5.7
=> A = 120 + 36 - 35
=> A = 156 - 35
=> A = 121
15.23 + 4.32 – 5.7 = 15.8 + 4.9 – 5.7 = 120 + 36 – 35 = 121
