Question

Pls Help me with this answer

Answer 1

Answer:

a. 5

b. -3

Step-by-step explanation:

a. (5*(8^1/3 + 27^1/3)^3)^1/4

= ((40^1/3 + 135^1/3)^3)^1/4

≈ ((3.42 + 5.13)^3)^1/4

≈ (8.55^3)^1/4

≈ 625^4

= 5

b. 64^-1/3*(64^1/3 - 64^2/3)

= 0.25*(4 - 16)

= 1/4 or 0.25 *-12

= -12*1 / 4

= -12/4

= -3

Hope this helped :3
