Math Problem Statement

(1/9)^(-1/2) + 4^2 * ∛(1/64) * (25)^(-1/2) + 27^(1/3) * (8)^(-1/3) ÷ √(4/9) - 4^0

Solution

The given mathematical expression is:

(19)12+421643×(25)12+2713(8)13÷(4940)\left(\frac{1}{9}\right)^{-\frac{1}{2}} + 4^2 \cdot \sqrt[3]{\frac{1}{64}} \times (25)^{-\frac{1}{2}} + 27^{\frac{1}{3}} \cdot (8)^{-\frac{1}{3}} \div \left( \sqrt{\frac{4}{9}} - 4^0 \right)

Let's simplify this step by step:

1. Simplify (19)12\left(\frac{1}{9}\right)^{-\frac{1}{2}}

(19)12=912=9=3\left(\frac{1}{9}\right)^{-\frac{1}{2}} = 9^{\frac{1}{2}} = \sqrt{9} = 3

2. Simplify 421643×(25)124^2 \cdot \sqrt[3]{\frac{1}{64}} \times (25)^{-\frac{1}{2}}

  • 42=164^2 = 16
  • 1643=1643=14\sqrt[3]{\frac{1}{64}} = \frac{1}{\sqrt[3]{64}} = \frac{1}{4}
  • (25)12=125=15(25)^{-\frac{1}{2}} = \frac{1}{\sqrt{25}} = \frac{1}{5}

So: 161415=1620=4516 \cdot \frac{1}{4} \cdot \frac{1}{5} = \frac{16}{20} = \frac{4}{5}

3. Simplify 2713(8)1327^{\frac{1}{3}} \cdot (8)^{-\frac{1}{3}}

  • 2713=327^{\frac{1}{3}} = 3 (since 27=3327 = 3^3)
  • (8)13=12(8)^{-\frac{1}{3}} = \frac{1}{2} (since 8=238 = 2^3)

So: 312=323 \cdot \frac{1}{2} = \frac{3}{2}

4. Simplify the denominator 4940\sqrt{\frac{4}{9}} - 4^0

  • 49=23\sqrt{\frac{4}{9}} = \frac{2}{3}
  • 40=14^0 = 1

Thus: 231=2333=13\frac{2}{3} - 1 = \frac{2}{3} - \frac{3}{3} = -\frac{1}{3}

5. Combine everything:

The full expression is: 3+45+32÷(13)3 + \frac{4}{5} + \frac{3}{2} \div \left(-\frac{1}{3}\right)

5.1 Simplify the division part:

32÷(13)=32×(3)=92\frac{3}{2} \div \left(-\frac{1}{3}\right) = \frac{3}{2} \times \left(-3\right) = -\frac{9}{2}

5.2 Combine all the terms:

Now we have: 3+45923 + \frac{4}{5} - \frac{9}{2}

To combine these, we need a common denominator. The least common denominator of 5 and 2 is 10:

  • 3=30103 = \frac{30}{10}
  • 45=810\frac{4}{5} = \frac{8}{10}
  • 92=4510-\frac{9}{2} = -\frac{45}{10}

So: 3010+8104510=30+84510=710\frac{30}{10} + \frac{8}{10} - \frac{45}{10} = \frac{30 + 8 - 45}{10} = \frac{-7}{10}

Final Answer:

The simplified value of the given expression is 710\frac{-7}{10}.
