Solve 80(30*6-10*34)^2/40*40*64*16=1.25

$$\frac { 80 ( 30 \times 6 - 10 \times 34 ) ^ { 2 } } { 40 \times 40 \times 64 \times 16 } = 1.25$$

Verify

Solution Steps

Cancel out 2\times 40 in both numerator and denominator.

$$\frac{\left(6\times 30-10\times 34\right)^{2}}{16\times 20\times 64}=1.25$$

Multiply 6 and 30 to get 180.

$$\frac{\left(180-10\times 34\right)^{2}}{16\times 20\times 64}=1.25$$

Multiply 10 and 34 to get 340.

$$\frac{\left(180-340\right)^{2}}{16\times 20\times 64}=1.25$$

Subtract 340 from 180 to get -160.

$$\frac{\left(-160\right)^{2}}{16\times 20\times 64}=1.25$$

Calculate -160 to the power of 2 and get 25600.

$$\frac{25600}{16\times 20\times 64}=1.25$$

Multiply 16 and 20 to get 320.

$$\frac{25600}{320\times 64}=1.25$$

Multiply 320 and 64 to get 20480.

$$\frac{25600}{20480}=1.25$$

Reduce the fraction \frac{25600}{20480} to lowest terms by extracting and canceling out 5120.

$$\frac{5}{4}=1.25$$

Convert decimal number 1.25 to fraction \frac{125}{100}. Reduce the fraction \frac{125}{100} to lowest terms by extracting and canceling out 25.

$$\frac{5}{4}=\frac{5}{4}$$

Compare \frac{5}{4} and \frac{5}{4}.
