202 x 12,5 x 50% + 202 : 4/5 + 202 : 0,4 + 1
giúp mik câu hỏi này vs nhé: 3^201+4^202+5^203
\(202x\frac{3}{4}+202x\frac{5}{4}+202x8\)
\(=202x\left(\frac{3}{4}+\frac{5}{4}+8\right)\)
\(=202x\left(\frac{8}{4}+8\right)\)
\(=202x\left(2+8\right)\)
\(=202x10\)
\(=2020\)
\(=202*(\frac{3}{4}+ \frac{5}{4}+8) = 202*9 = 1818\)
202 x \(\frac{3}{4}\) + 202 x\(\frac{5}{4}\) + 202 x 8
= 202 x ( \(\frac{3}{4}\)+\(\frac{5}{4}\)+ 8 )
= 202 x ( \(\frac{8}{4}\)+ 8 )
= 202 x ( 2 + 8 )
= 202 x 10
= 2020 .
2^2020 : 2^x=202
giải nhanh giúp mềnh
Tính bằng cách thuận tiện:
50 x 125 x 2 x 8 x 202
50 x 125 x 2 x 8 x 202
= (50 x 2) x (125 x 8) x 202
= 100 x 1000 x 202
= 100000 x 202
= 20200000
=(50x2)x(125x8)x202
=100x1000x202=100 000x202=202 00000

Giúp mik nhanh nha
i) 48:x=46

m)(x2-10):5=3
ghi chi tiết giúp tớ nhé,tớ đag rất gấp ạ
a,4^8:X=4^6
X=4^8:4^6
X=4^2
b,12x-33=3^5
12x-33=243
12x=243+33
12x=276
12*X=276
X= 276:12
x=23
c,(5x+335):2=20^2
(5x+335):2=400
(5x+335)=400*2
(5x+335)=800
5*x+335=800
5*x=800-335
5*x=465
x=465:5
x=93
d, (x^2-10):5=3
x^2-10=3*5
x^2-10=15
x^2=15+10
x^2=25
x^2=5^2
vậy x=5
e,740:(x+10)=10^2 - 2*13
740:(x+10)=10^2-26
740:(x+10)=100-26
740:(x+10)=74
x+10=740:74
x+10=10
x=10-10
x=0
nhớ tik cho mik nhé
