\(160-\left(2^3.5^2-6.25\right)\)
\(=160-\left(8.25-6.25\right)\)
\(=160-\left[25.\left(8-6\right)\right]\)
\(=160-50\)
\(=110\)
giup minh bai nay
160-[2^3.5^2-6.25]
Giải gúp mình nhé!
160-(2^3.5^3-6.25)=
\(3.8.5^2+2.4^3.12+\left(2^3+3\right).6.4\)
\(600:\left\{450-\left[450-\left(2^3.5^2\right)\right]\right\}\)
tính rồi phân tích ra thừa số nguyên tố
160-(23.52-6.25)
\(A=6.25-\left(61-17\right).12+\left(27+24\right):17\)
\(B=\left(-126\right)-\left(4^2-5^2\right)+870:29\)
\(7^2.5-\left(2x+1\right)=630:9\)\(\)
\(\left(12-4x\right)+120:23=17\)
\(2.\left(-3\right)^2+\left(-2\right)^3.5\)
\(2.\left(-3\right)^2+\left(-2\right)^3.5\)
\(\frac{\left(2^3.5^4.11\right).\left(2.5^3.11^2\right)}{\left(2^2.5^311\right)^2}\)
\(50-\left[\left(50-2^3.5\right):2+3\right]\)
