a)-8

b)1525

Giải chi tiết giúp mình nha

1: =29-16-3*2=13-6=7

2: =35-12+(-14)-2

=23-16=7

3: =4*3125-32:16

=12500-2

=12498

4: =-452+67-75+452=-8

5: =18+99*18-3^5-2^5

=1800-275

=1525

Đáp án: A

3 3 . 3 2 = 3 5  = 243

a:\(A=3^9\cdot3^8\cdot\left(-3^5\right)=-3^{22}\)

b: \(B=5^3+3^5=125+243=368\)

c: \(3C=3^{101}-3^{100}+3^{99}-...-3^2+3\)

\(\Leftrightarrow4C=3^{101}+1\)

hay \(C=\dfrac{3^{101}+1}{4}\)

a)  B   =   3 3 . 3 2   + 2 2   + 3 2 = 256 = 16 2 .

b)  D   =   5 . 4 3   +   2 4 . 5 = 400 =  20 2

\(A=2^5.5^2-3^2-10\\ \\ A=32.25-9-10=800-9-10\\ \\ A=781\)

\(B=3^3.3^2+2^2+3^2\\ \\ B=3^{3+2}+4+9\\ \\ B=3^5+13=243+13\\ \\ B=256\)

\(328-\left[x-\left(33.32-29:22\right).2\right]=274\)

\(328-\left[x-\left(1056-\frac{29}{22}\right).2\right]=274\)

\(x-2112+\frac{29}{11}=328-274\)

\(x-2112+\frac{29}{11}=54\)

\(x=54+2112-\frac{29}{11}\)

\(x=\frac{23797}{11}\)

vậy \(x=\frac{23797}{11}\)

a, A =  2 2 . 5 2 - 3 2 - 10 = 81 =  3 4 = 9 2

b, B =  3 3 . 3 2 + 2 2 + 3 2 = 256 =  16 2 = 2 8 = 4 4

c, C =  5 . 4 3 + 2 4 . 5 = 400 =  20 2

d, D =  5 3 + 6 3 + 7 3 + 79 . 2 2 = 1000 =  10 3

a)  A = 2 5 . 5 2 - 3 2 - 10 = 81 = 3 4 ( = 9 2 ) .

b)  B = 3 3 . 3 2 + 2 2 + 3 2 = 256 = 16 2 ( = 2 8 = 4 4 ) .

c)  C = 5 . 4 3 + 2 4 . 5 = 400 = 20 2

d)  D = 5 3 + 6 3 + 7 3 + 7 9 . 2 2 = 1000 = 10 3 .
