Question

2a-28 Evaluate the exponent expression for a = 1 and b= -2.

Answer 1

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data

a = 1

b= -2

Step 02:

`(a^(-3))/(2a^(-2)b^3)=(1^(-3))/(2\cdot(1)^(-2)\cdot(-2)^3)^{}`
`(1^(-3-(-2)))/(2\cdot(-2)^3)=(1^(-1))/(-16)=(-1)/(16)`

The answer is:

- 1 / 16
