Viết các tích sau dưới dạng lũy thừa:
a. \(8^4.16^5.32=2^{12}.2^{20}.2^5=2^{37}\)
b.\(27^4.81^{10}=3^{12}.3^{40}=3^{52}\)
a) 84 . 165 . 32
= (23)4 . (24)5 . 25
= 212 . 220 . 25
= 237
b) 274 . 8110
= (33)4 . (34)10
= 312 . 340
= 352
a. \(\left(-8\right).\left(-3\right)^3.125=\left(-2\right)^3.\left(-3\right)^3.5^3=\left[\left(-2\right).\left(-3\right).5\right]^3=30^3\)
b. \(27.\left(-2\right)^3.\left(-7\right).49=3^3.\left(-2\right)^3.\left(-7\right)^3=\left[3.\left(-2\right).\left(-7\right)\right]^3=42^3\)
a)=(-2)3.(-3)3.53
=[(-2)(-3)5]2
=303
b)=33.(-2)3.(-7)(-7)2
=33.(-2)3.(-7)3
=[3(-2)(-7)]3
