Solution

\frac{8}{9}

+1

Decimal Notation

0.88888 \dots

Solution steps

8 \cdot 3^{- 2}

Apply exponent rule:

a^{- b} = \frac{1}{a ^{b}}

3^{- 2} = \frac{1}{3 ^{2}}

= 8 \cdot \frac{1}{3 ^{2}}

3^{2} = 9

= 8 \cdot \frac{1}{9}

8 \cdot \frac{1}{9} = \frac{8}{9}

= \frac{8}{9}

\frac{55 x ^{7} y ^{6}}{11 x ^{11} y ^{8}}

12(x-1)=-6(2-x)+6x

12 (x - 1) = - 6 (2 - x) + 6 x

\frac{11 u}{3} \leq \frac{2}{9}

x^{2} + 6 x + 3 = 0

factor x^3-6x^2+8x factor

x^{3} - 6 x^{2} + 8 x
