3道积的乘方(简便运算+过程)
(1)2^5*5^4
(2)8^8*(-1/4)^12
(3)(-3)^5*(-2/3)^5*(-5)^6
就这3题,要简便运算和完整过程啊~~~!

3道积的乘方(简便运算+过程)(1)2^5*5^4 (2)8^8*(-1/4)^12(3)(-3)^5*(-2/3)^5*(-5)^6就这3题,要简便运算和完整过程啊~~~!2^5x5^48^8x(-1/4)^12(-3)^5x(-2/3)^5x(-5)^6
(1)2^5*5^4 =2*2^4*5^4=2*(2*5)^4=20000
(2)8^8*(-1/4)^12 =8^8*(1/4)^12 =2^24*(1/2)^24=(2*1/2)^24=1
(3)(-3)^5*(-2/3)^5*(-5)^6=[(-3)*(-2/3)]^5*5^6=2^5*5^5*5=(2*5)^5*5=500000
(1)=10^4×2=20000
(2)=4^(8×2-12)=4^4=256
(3)(-2)^5×(-5)^6=500000
你写的题目有些符号看不懂呀.不会写.
(1)2^5*5^4 =(2*5)^4*2 =20000
2) 8^8*(-1/4)^12 =(2^3)^8*((1/2)^2)^12
=2^24 *(1/2)24 =((1/2)*2)^24=1
(3)(-3)^5*(-2/3)^5*(-5)^6
=((-3)*(-2/3))^5*5^6
=2^5*5^6 =(2*5)^5*5 =500000
(1)原式=(2*5)^4*2=10000*2=20000
(2)原式=(8*1/4)^8*(1/4)^4=2^8*(1/4)^4=(2*1/4)^4*2^4=(1/2*2)^4=1
(3)原式=(-3*-2/3*-5)^5*(-5)=(-10)^5*(-5)=500000
