\(187-\left(24-5.3\right)^2=187-\left(24-15\right)^2=187-9^2=187-81=106\)

\(75-\left(3.5^2-4.2^3\right)=75-\left(75-32\right)=75-43=32\)

\(80-\left(4.5^2-3.2^3\right)=80-\left(100-24\right)=80-76=4\)

mọi người giúp mình với mình cầ gấp 

mình cảm ơn mọi người trước nhaaaaaaaaaaaaaaaaaaaaaaaaa

a)187-(24-15)=187-9=178

b)75-(75-16)= 75-59=16

c)80-(100-24)=80-76=4

ok rồi nha bạn nhớ k đúng cho mình nha

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

\(4\cdot5^2-3^2\cdot\left(2021^0+3^2\right)\)
\(=4\cdot25-9\cdot\left(1+9\right)\)
\(=100-9\cdot10\)
\(=100-90\)
\(=10\)

4. 5²- 3². ( 2021⁰+ 3²)

= 4 . 25 - 9 . ( 1 + 9 )

= 100 - 9 . 10

= 100-90

= 10

312 + (146 -X ) =401

11- (15 + 21 ) + X- (25-9)

2- X +177 - (-5) 

X -12 = (-9) - 15 

1,

\(75-\left(3.5^2-4.2^3\right)=75-\left(75-32\right)=75-75+32=32\)

2,

\(58.76+24.58-5.20=58\left(76+58\right)-100=58.100-100=100\left(58-1\right)=5700\)3,

\(4.5^2-3.2^3+3^3:3^2=4.5^2-3.2^3+3^{3-2}=3\left(2^3+1\right)+100=27+100=127\)4,

\(\left[5^2.6-20\left(37-2^5\right)\right]:10-10^0=\left(5^2.6-20.5\right):10-1=\left[10\left(15-10\right)\right]:10-1=5-1=4\)cái đề bn ghi ko rõ nên mk lầm thì báo mk nhé

a: \(=\left\{145-\left[130-10\right]:2\right\}\cdot5\)

\(=\left\{145-60\right\}\cdot5=85\cdot5=425\)

b: \(=100:\left\{250:\left[450-4\cdot125+4\cdot25\right]\right\}\)

\(=\dfrac{100}{250:\left[450-500+100\right]}=\dfrac{100}{250:50}=\dfrac{100}{5}=20\)

c: \(=355-5\cdot\left[64-\left(27-25\right)\right]=355-5\cdot\left[64-2\right]\)

\(=355-310=45\)

a: \(=32-76=-44\)

b: \(=20-30+4^2=-10+16=6\)

\(B=5.3^2+4.3^2=3^2\left(5+4\right)=9.9=9^2\)

\(C=5^3+6^3+59=125+216+59=400=20^2\)

\(D=5.4^3+2^4.5+41=320+80+41=441=21^2\)

b: \(5\cdot3^2+4\cdot3^2=3^2\cdot9=3^4\)

c: \(5^3+6^3+59=20^2\)

\(5\cdot4^3+2^4\cdot5+41=21^2\)
