Question

Simplify the expressions:
1) $\sqrt{x^6}$ where x<0
2) $\sqrt{m^4}$
3) 1.5 * $\sqrt{t^1 ^4}$ where t<0

Answer 1

Answer:

1. -x³

2. m²

3. -1.5t⁷

Step-by-step 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
