Question

10.(n^8)^4

13.(x^⅔)^10

16.d(d^-2)^-9

20.(t^2)^-2(t^2)^-5

24.(5y^½)^4

27.(2y^7/5)^-3

30.(3b^-2)^2(a^2b^4)^3

33.(2j^2k^4)^-5(k^-1j^7)^6

For 36 and 39, write the answer in scientific notation.

36.(2x10^-10)^3

39.(6.25x10^-12)^-2

Answer 1

10) (n^8)^4 = n^(8x4) = n^32

if n= 2, (n^8)^4 = (2^8)^4 = 256^4 = 4.2949673 x 10^3 = 2^32

13) (x^2/3)^10 = x^(20/3)
