Solve (-15)^4:(-15)^5:(-15)^0

$$( - 15 ) ^ { 4 } : ( - 15 ) ^ { 5 } : ( - 15 ) ^ { 0 }$$

Evaluate

$$-\frac{1}{15}\approx -0.066666667$$

Solution Steps

Rewrite \left(-15\right)^{5} as -15\left(-15\right)^{4}. Cancel out \left(-15\right)^{4} in both numerator and denominator.

$$\frac{\frac{1}{-15}}{\left(-15\right)^{0}}$$

Fraction \frac{1}{-15} can be rewritten as -\frac{1}{15} by extracting the negative sign.

$$\frac{-\frac{1}{15}}{\left(-15\right)^{0}}$$

Calculate -15 to the power of 0 and get 1.

$$\frac{-\frac{1}{15}}{1}$$

Anything divided by one gives itself.

$$-\frac{1}{15}$$

Factor

$$-\frac{1}{15} = -0.06666666666666667$$
