Question

(1 / 4 × 1 / 3)^2*9*5^2=

Answer 1

(1 / 4 × 1 / 3)^2*9*5^2=(1 / 4)^2 × (1 / 3)^2*9*5^2=1/16*1/9*9*25=25/16=1 9/16

Answer 2

To solve this expression, let's break it down step by step:

(1 / 4 × 1 / 3)^2 * 9 * 5^2

Step 1: Simplify the fraction inside the parentheses.

1 / 4 × 1 / 3 = 1 / 12

Now, the expression becomes:

(1 / 12)^2 * 9 * 5^2

Step 2: Square the fraction inside the parentheses.

(1 / 12)^2 = 1 / 144

The expression now looks like this:

(1 / 144) * 9 * 5^2

Step 3: Calculate 5^2.

5^2 = 25

Now we have:

(1 / 144) * 9 * 25

Step 4: Multiply the numbers together.

(1 / 144) * 9 * 25 = 0.140625 * 9 * 25 ≈ 31.640625

So, (1 / 4 × 1 / 3)^2 * 9 * 5^2 is approximately 31.640625.
