Question

in 9 - 12, evaluate each power or expression. 9. 9³ 10. (1/4)³ 11. - 0.5² 12. 1.5×10²

Explanation:

Step1: Evaluate $9^3$

$9^3=9\times9\times9 = 729$

Step2: Evaluate $(\frac{1}{4})^3$

$(\frac{1}{4})^3=\frac{1}{4}\times\frac{1}{4}\times\frac{1}{4}=\frac{1}{64}$

Step3: Evaluate $- 0.5^2$

$-0.5^2=-(0.5\times0.5)= - 0.25$

Step4: Evaluate $1.5\times10^2$

$1.5\times10^2=1.5\times100 = 150$

Answer:

$9^3 = 729$, $(\frac{1}{4})^3=\frac{1}{64}$, $-0.5^2=-0.25$, $1.5\times10^2 = 150$
