Answer:
D. 8.4* 10^8
Step-by-step explanation:
A. =4^(-11/3)*4^(2/3)
=4^(-9/3)
=4^(-3)
=1/64
Second line on the right side of the equation it should be 2x(-13)
so then 8x - 24 + 7 = -26x
8x - 17 = -26x
then in hers she added the 8 to 26 when she should have subtracted it
it should be -17 = -34x
so 17 = 34x
1/2 = x
Hhhhhhhhahahahahahahahahahahaahabahahah 4.7
