\(=100:\left[250-450+4\cdot125-8\cdot25\right]\\ =100:\left[-250+500-200\right]=100:50=2\)

\(4^{250}=\left(2^2\right)^{250}=2^{500}=\left(2^5\right)^{100}=32^{100}\)

Vì \(32^{100}>25^{100}\)nên \(4^{250}>25^{100}\)

gíup em vs ạ

\(d,100:\left\{250:\left[450-\left(4.53-22.25\right)\right]\right\}\)

\(100:\left\{250:\left[450-\left(4.5^3-3^2.25\right)\right]\right\}\)

\(100:\left\{250:\left[450-175\right]\right\}\)

\(100:\left\{250:275\right\}\)

\(=100:\dfrac{10}{7}\)

\(=100.\dfrac{7}{10}\)

\(=70\)

bài này của bạn làm sai rồi.kết quả là 20

134 x 100 + 250 x 100 - 84 x 100

= (134 + 250 - 84 ) x 100

= ( 384 - 84 0 x 100

= 300 x 100

= 30000

a, 13104

b,134*100+250*100-84*100=100*(134+250-84)=100*300=30000

134*100+250x100-84x100

=100x(134+250-84)

=100x300

=30000

a) \(\dfrac{7}{4}\text{⇔}1\dfrac{3}{4}\text{⇔}1,75\text{⇔}\dfrac{175}{100}\text{⇔}175\%\)

b) \(\dfrac{12}{5}\text{⇔}2\dfrac{2}{5}\text{⇔}2,4\text{⇔}\dfrac{240}{100}\text{⇔}240\%\)
