giúp mk vớiiiiiiiiiii
tinh nhanh 1500-{5^3.2^3-11.[7^2-5.2^3+8.(11^2-121)]}
1. 3.2x - 3 = 45
2 . 4x3 + 12 = 120
3 . 2x - 138 = 23 . 32
1 . 3.2x - 3 = 45
2 . 2448 : [ 119 - ( x - 6 ) ] = 0
3. 4x3 + 12 = 120
\(\dfrac{1}{55^2}\).\(5^4\).(-11)\(^2\) . \(55^5\) . (\(\dfrac{1}{5^2}\))\(^2\) : (\(5^3\) . \(11^6\)
Tìm x, biết
a) 6x + x = 511 : 59 + 31
b) 7x – x = 521 : 519 + 3.22 - 7^0.7
c)2x+1 . 22009 = 22010
d) 1+2+3+….+x = 55
e) x – 48 : 3 = 12
f) (2x + 5) .|-7| = 73
tính nhanh:
a) \(A=1500-\left\{5^3.2^3-11.\left[7^2-5.2^3+8\left(11^2-121\right)\right]\right\}\)
