Question

1) viết kết quả phép tính dưới dạng một lũy thừa:

a) 3⁴. 5⁴

b) 8³. 32⁴

c) 49² . 7⁵

d) 2³.4³. 16⁴

Answer 1

a, \(3^4.5^4=\left(3.5\right)^4=15^4\)

b, \(8^3.32^4=\left(2^3\right)^3.\left(2^5\right)^4=2^9.2^{20}=2^{29}\)

c, \(49^2.7^5=\left(7^2\right)^2.7^5=7^4.7^5=7^9\)

d, \(2^3.4^3.16^4=2^3.\left(2^2\right)^3.\left(2^4\right)^4=2^3.2^6.2^{16}=2^{25}\)

Chúc bạn học tốt!!!

Answer 2

a) \(3^4.5^4=\left(3.5\right)^4=15^4\)

b) \(8^3.32^4=\left(2^3\right)^3.\left(2^5\right)^4=2^9.2^{20}=2^{29}\)

c) \(49^2.7^5=\left(7^2\right)^2.7^5=7^4.7^5=7^9\)

d) \(2^3.4^3.16^4=2^3.\left(2^2\right)^3.\left(2^4\right)^4=2^3.2^6.2^{16}=2^{25}\)

Chúc học tốt!!!
