Question

(1.3-10³):(65*10²) Записати у стандартному вигляді

Answer 1

$(1.3 - 10 {}^{3} ) \div (65 \times 10 {}^{2} ) \\ ( \frac{13}{10} - 10 {}^{3} ) \div (65 \times 100) \\ \frac{13 - 10 {}^{4} }{10} \div 6500 \\ \frac{13 - 10000}{10} \times \frac{1}{6500 } \\ \frac{ - 9987}{10} \times \frac{1}{6500} \\ - \frac{9987}{65000}$

Answer 2

To simplify the expression (1.3 - 10³) : (65 * 10²) and write it in standard form, follow these steps:

Step 1: Perform the calculations inside the parentheses. 1.3 - 10³ = 1.3 - 1000 = -998.7

Step 2: Divide the result from Step 1 by the product of 65 and 10² (which is 6500). -998.7 / 6500 ≈ -0.1536 (rounded to four decimal places)

Therefore, the simplified expression in standard form is approximately -0.1536.
