Question

Write each expression so that all exponents are positive.
a b⁻¹ c²

Answer 1

`(ac^2)/(b)`

Explanation:

`b^(-1)=(1)/(b)\\a(1)/(b)c^2\\a\cdot (b)/(c)=(a\cdot \:b)/(c)\\(a\cdot \:1\cdot \:c^2)/(b)\\a\cdot \:1\cdot \:c^2=ac^2\\(ac^2)/(b)`

Answer 2

`\frac{a}{bc {}^(2) }`

Explanation:

Here use the property of -ve exponents.

According to that if you have -ve exponent, just flip the base and change the exponent to positive.

b is a base with -1 exponent and c is another base with -2 exponent.

so flip the base and change the negative exponent into positive exponent.

`\frac{a}{bc {}^(2) }`
