4^6x9^5+6^9x120/8^4x3^12-6^11
= (2^2)^6.(3^2)^5 + (2.3)^9.3.5.2^3 / (2^3)^4.3^12 - (2.3)^11
= 2^12.3^10 + 2^9.3^9.3.5.2^3 / 2^12.3^12 - 2^11.3^11
= 2^12.3^10 + 2^12.3^10.5 / 2^11.2. 3^11.3 - 2^11.3^11
= 2^12.3^10.(1+5) / 2^11.3^11.(6-1)
= 2^12.3^10.6 / 2^11.3^11.5
= 4/5
Tính:
A) 212.35 -46.36/ 212.93+84.35
B) 496.5-711/(-7)10.5+2.495
Tính giá trị các biểu thức sau
f) \(\left(1:\frac{1}{7}\right)^2\left[\left(2^2\right)^3:2^5\right]\frac{1}{49}\)
g)\(\frac{4^6.3^5-2^{12}.3^6}{2^{12}.9^3+8^4.3^5}\)
Rút gọn theo cavhs hợp lí:
1, \(\frac{131.145+100}{45-132.145}\)
2,\(\frac{49^6.5-7^{11}}{\left(-7\right)^{10}.5+2.49^5}\)
PS: bn nào giải đcj giúp mik bài này sẽ đc 3 l ike
Rút gọn một cách hợp lí:
1, M= \(\frac{131.145+100}{45-132.145}\)
1, N=\(\frac{49^6.5-7^{11}}{\left(-7\right)^{10}.5+2.49^5}\)
B=2^12.3^5-4^6.9^2/(2^2.3)^6+8^4.3^5-5^10-25^5.49^2/(125.7)^3+5^9.14^3
2^12.3^5-4^6.9^2/(2^2.3)^6+8^4.3^5-5^10.7^3-25^5.49^2/(125.7)^3+5^9.14^3
(2^12.3^5-4^6.9^2) / [(2^2.3)^6 +8^4.3^5] - (5^10.7^3-25^5.49^2) / [(125.7)^3+5^9.14^3]
