Question

Simplify the expressions:

1)
`√(x^6)` where x<0
2)
`√(m^4)`
3) 1.5 *
`√(t^1 ^4)` where t<0

Answer 1

1. -x³

2. m²

3. -1.5t⁷

Explanation:

x⁶^½ = +/- x³

Since x is negative, postive square root would be -x³

m⁴^½ = +/- m²

Positive square root is m²

t¹⁷^½ = +/- t⁷

Since t is negative, postive square root would be -t⁷

1.5 × -t⁷ = -1.5t⁷
