Question

tính

1, 75-(3.5 mũ 2 -4.2 mũ 3)

2, 58.76+24.58-5.20

3, 4.5 mũ 2 - 3. 2 mũ 3 + 3 mũ 3 : 3 mũ 2

4, [ 5 mũ 2 6 - 20(37-2 mũ 5) ]: 10 - 10 mũ không

Answer 1

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
